(Bihter & Behlul dislike each other, Behlul think if Bihter is marrying his uncle for his wealth whereas Bihter hate him to cheat her sis). They first met each other when Bihter has come to see off Peyker whilst Behlul has come there to receive Elif.
Mr Adnan soon pay a visit to Bihter's mom & set his proposal before her. Firdous who was thinking if he has come to propose her, starts shouting and creating a sort of drama for the age differences between her daughter & the person (oldie :/ ). However Bihter , the clever girl somehow mange to marry him. She then visit Ahsen (Adnan's sis) along with Peyker & Firdous. Where Behlul closely noticed her with his uncle.
Soon after the visit Adnan and Bihter get married where Hilmi creates a drama by sending a tape (before he also has told Adnan that he is making a big mistake by
marrying Firdous' daughter Bihter and warns him that Firdous will rob
his family just like she did to Nihat but Adnan ignores him) Behlul however managed the situation.


Bihter and Adnan starts living a happy life. Bihter tries to be good
towards Adnan's children. Now everything is going well. Bihter gets
pregnant with Adnan's child. Her mother Firdevs becomes excited and says
this child will ensure Bihter's position in Ziyagil family. But Bihter
is not ready for the child so early. She talks to Adnan about it that
his children have not accepted Bihter yet. She wants to give them more
time so they can get attached with her completely. He says we will talk
later on it and also that he will be with her in her decision but he
wanted to think over it again. Bihter aborts the child without informing
Adnan and he gets tensed. Some problems between Bihter and Adnan arise
due to this but then these are resolved.
Now what .. ?
They marry & then live happily ever after ?
right!
oh no ..
how's that possible by keeping petrol with a fire & imagining if it would not burn.
stupidity, I must say! :/
Poor oldie keep his sexy wife & hottie nephew together under one roof..
so silly he was to do that ! :/
Mr Behlul now is with Elif (his GF),
& then alluring Bihter (with much shorter & hotter dresses) start gaining his attention. Poor flirty , compelled by his habit , is distracted by the sexy aunt (of course any person would).
When Adnan got a love letter of Behlul praising Peyker and mistook if it was for Bihter. He called them both and ask about it then Behlul told him the truth.
The family then celebrates new year at Ahsan's farmhouse where Adnan in a sense of apologize gifts Behul a car and then ask Bihter and Behlul to dance together that they both enjoys much.
Family enjoys the night and greet each other with presents for new year.
On the next day Bihter follows Behlul to clear the all misunderstandings created by the letter where Behlul denies to listen her that make Bihter angry but she told him that it was not her fault, Peyker has asked her to burn all those letters so that Nehat wouldn't read them but unfortunately she missed that one and Adnan caught it.
They both then make up the confusion and start their friendship that actually led them in the worst situation afterwards.
The family then plan a trip to Paris & western areas whereas Behlul denied to join them so that he could enjoy with Elif in Ziyagill's mansion. Adnan along with his family is happily enjoying vacations when a day suddenly Behlul arrived and surprised them. All are really happy (specially Nehal, she has some soft feelings for her cousin), their Bihter start taking more interest in him , Behlul noticed it and ask her to stay away where Bihter is in state of shock (before it , Behlul has caught her in his room, smelling his perfume and thus came to know that she shares the mutual feeling of attraction as he does.),
Bihter there punt him that he won't marry Elif , Behlul then accept the challenge & bet a perfume as a reward.
They are now back to Istanbul, Behlul fixes a meeting of his uncle to Elif's parent so that they could mingle along & set a date for their engagement where Bihter get to know through Peyker that Hilmi these days is cheating on his wife for Elif. Bihter then planned them to meet at the place where Hilmi is sharing his holds, she somehow managed the situation so that Behlul would get to know about it. Behlul however didn't take the situation seriously (for winning his bet actually) but he is getting more interested in his aunt day by day. He ask her to leave him alone or if she has any soft feelings,
Bihter get angry with him and then start ignoring him, so he started jealousing her by kissing or praising Elif in her front.
He , on his engagement with Elif feel loved for Bihter and got distracted by her physical beauty and sexiness. Bihter has wore alluring Orange dress that has incremented her beauty by many times.
He couldn't control himself falling for her and thus say these beautiful lines :
I am in Pain,
My Heart is guilty,
My Brain is guilty,
Tonight, I've feel the most,
What I WISH really meant...
After the engagement party, Behlul is playing Piano on the request of Ahsan and Nehal when Bihter come to the room and her heart goes with the flow of the music, just after he stopped playing it she leaves the room and come at the back of the
mansion,
where Behlul follows her and tried to kiss & seduce Bihter, Bihter pushes him
away and run towards her room, where Behlul is kinda surprised of what
he had done whilst Bihter is hurt and crying.

Mrs Firdous knew all the truth of what is going on between Bihter and Behlul by spying on her through her maid Katiya and warn Bihter to move back but Bihter denies her by saying she has got it wrong. They fight even more on this subject. Bihter even tries to
kick Firdevs out of the house, but Firdevs threatens her to tell
everything to Adnan. Behlul drink all the night with Captain Raza (he will be Nasreen's fiancee later) that drives him unconscious, Raza calls Adnan and tells him Behlul's condition and ask him to come to receive Behlul. Mr Adnan along with Bashir took Behlul to home, where Behlul is still not in his conscious tells Bihter about his love which she cleverly cope up with the situation before Adnan. Next day Elif send her rings back to Behlul , telling she don't to want to be in relationship with him any more. Bihter has now also grown mushy feelings for Behlul and accepted before him her love. Firdovs finds out about Deniz’s secret feelings for Adnan and tells
Bihter about it. Bihter gets angry and tries to send Deniz away, but
then she stops because she thinks that Deniz might also know about her
passion for Behlül.

It gives Behlul confidence and he start doing these creepy things with Bihter every time
he find her alone, They kiss, hug and even intercourse sex.
Behlul broke up with Elif and according to the bet ,
Behlul give Bihter a Perfume. He also buys a small house on the riverside (RIVA) but only Bihter is aware of it. Bihter often goes there to meet Behlul.Their they both carried out their lusty and filthy feelings.
God knows what it was?
Either Lust or Love!
That destroys respect and loyalty of every relation, they both were deceiving.
It was forbidden Love and it needs to come to an end, the disastrous end.
They both were making love at the workshop of Adnan where Bashir make their video but hide it from others, for he doesn't want to hurt Nehal (whom he loves secretly) and Adnan.

Bihter realizes that it must be Bashir who saw her with Behlul.
Especially when Bashir tries to talk to Adnan in private, her suspicion
becomes true. In the meantime, Behlul's former fiancé, Elif, has spread
the rumor that Behlül and Nihal are only distant cousins and thus secret
lovers. While the entire family is angry, Nihal seems to like the idea. Bihter tell ale this to Behlul who got horrified by the news when Nihal comes to visit Riva. Bihter managed to escape but had an accident on her way that disturbed the whole family, Adnan as well as Behlul are worried about Bither's accident. Bither is
only mildly injured in the car crash. She was on her way to tell Adnan
everything about her and Behlul. Behlul cries loud, and come to see Bihter while
Firdous caught him kissing Bihter on her hands. Even after the accident she is
convinced to tell Adnan everything. However, Behlul somehow convince her to stop.

Bihter, now is deeply in love with Behlul and she doesn't want to lose him at any cost. She asks him to fly away so that she could divorce Adnan and they both will live happily. Behlul agrees to do so but at the very last moment when they were just about to fly he denies to go and come back to the mansion.
Bihter is much upset on Behlul's cowardice and to avenge him and his inability to stand by her side Bihter returns to
her husband. she start paying more attention on her husband. She many times kissed
Adnan in front of Behlul to jealy him,
Behlul got depressed and rest a
night in Riva with his ex-gf where Bihter caught him cheating. They
fought and broke up.
Meanwhile, trying to make Bihter forget about her passion for Behlul,
Firdous finds out about Nihal’s feelings for the same Behlul. She tries
to bring them together. After a while, she even reveals this to Adnan.
Bihter gets angry with her mothers schemes one more time. Behlul is now guilty for cheating on his uncle and left Bihter, Bihter couldn't take the situation and start pinching Behlul for not doing so. Behlul now is moving towards Nehal , the innocent cousin. Bihter and Behlul again had a bet for the engagement.
Behlul proposes on Nihal and Adnan gratefully agrees to see his daughter really happy, they successfully had their engagement. Bihter is destroyed to see Nihal and Behlül engaged, but manages to hide her feelings to the rest of the family.
English Translation Of The Song o Nihal's and Behlul's engagemnent...
This song is from Bihter and Behlul's aspect and reflects their feelings
Female: A page is tearing from the time
As you're leaving me (behind)
Male: Of this love, from the very beginning
It was its ending that I feared
Female: I've hidden you like a sin
Me with you, no one has seen
Both: My eyes smiled as my inside cried
It was Like a sin that I had to hide
Female: Neither from today nor from the next
What's left that I'm going to expect
Male: Jealous of me that day because of you
Those Pictures have turned pale
Both: I've hidden you like a sin
Me with you, Nobody has seen
My eyes smiled as my inside cried
It was Like a sin that I had to hide
Bihter is again pregnant of Behlul's child, she tells him about pregnancy for which he neg accepting it his child and even he denies if Bihter really is pregnant and take the situation as Bihter's clever plan. Firdous finds out the pregnancy and calls Adnan, Adnan is really happy but when he ask Bihter about she denies and call Firdous a lier. This time it is dangerous for her to abort the child but when Behlul denies accepting it and has moved towards Nihal, she aborts it on the risk of her life. (At the very moment, I for the very first time feels her pain, she wasn't the only to sin but she was suffering it alone.)
Behlul finds her in pain and later ask her the truth but it was too late, she ignores him and didn't share her pain with anyone.
Bihter found Nihal and Behlul affectionately in real love that hurts her ego and self respect, she in anger broke the mirror that Behlul has gifted her before. Mrs Firdous has been engaged with Chetin (another rich tycoon) and Bihter is in shock how her mom always got what she wants.
Behlul and Nihal throw a party for deciding their wedding date. Bihter was much heart broken and upset of the fate. She quote the same words as Behlul did on his engagement with Elif.
I am in Pain,
My Heart is guilty,
My Brain is guilty,
Tonight, I've feel the most,
What I WISH really meant...
After a few days, Chetin throws a party at his house, to celebrate
his engagement to Firdous with their family and friends. Bihter tells
her mother that she cannot stand to see Nihal and Behlul living their
love in front of her eyes. She asks Firdous to stop the imminent wedding
by any means. Firdous promises her that she will do so, realizing for the
first time how much Bihter was actually suffering.

Nihal and Behlul go on with their wedding preparation and Nihal is very
excited, looking for honeymoon destinations and talking about her dress.
Firdous doesn’t know how to stop this, but she knows she has to keep
her promise. whilst trying to do so Peyker and Nihat caught her and came to know the whole truth of Bihter & Behlul. (Meanwhile, Hilmi sends to Adnan a copy of the key from Behlul’s house
on the beach at Riva and a note, telling him to go and check the place
because he might find interesting things. This is why she left home in
the first place, when Adnan told her about the key. Trying not to look
guilty of adultery, Bihter pretended she’s the victim and left angry.
Later she started feeling guilty for real and she wanted to tell Adnan
the whole truth. Rushing to him, Bihter had a car accident, which
brought her back home eventually. )
Nihal with Adnan and rest of the family decides to give Behlul a
surprise birthday party but they were confused how to call Behlul there
without breaking the secret of the surprsi, Bihter took it as her
responsibilty, she called Behlul and said that she now wants to meet him
for the last time and to spend time with him and then they will broke
apart. Behlul , even engaged to Nihal, agrees to do so. He got ready ,
pour perfume and reached the venue, but ramained all surprised and
shocked by Seeing all of the family and crowd over there. (LOL his
expressions were worth enjoying, Bihter after much time laugh and enjoys
the whole party , singing and dancing for she today understand how much
he really loves her.)

Bihter left the mansion, Behlul came to visit her and accused her for all what happened. Shame
on him for being such a weak man. He was accusing Bihter for all the
things that he and Bihter did together. He doesn't remember that he was the one who started it all and
didn't back out when Bihter refused him and resisted him. He was the one
keen on betraying his uncle and then he blame Bihter for betraying her
husband but he doesn't see how he repaid his father-like uncle who gave
him everything. Behlul wass even worse because he was betraying everyone. On the other hand, Bihter should have confessed to Adnan herself as Behlul can't be trusted with this.

Bihter realizes that Firdous can’t do anything to break up Nihal and Behlul
, Bihter is ready
to leave again and take Behlul with her this time. Behlul tells her
constatly that she is insane and that he can’t do this to his uncle,
Adnan, who raised him and gave him everything. Behlul misbehaves with her saying she is second Firdous that really hurts her but now it becomes impossible for her to forget Behlul and to watch him living under the same roof with someone else.
Even if she didn't try stopping him, it then make the chance that after marriage Behlul would have continue his relation with Bihter too. As after engagement with Nihal, he has many times kissed Bihter.
Behlul was coward enough not to take any stand or may be it was his greed. He has always loved Bihter but this time by cheating on her he's not only hurting her but himself too.
Actually it was the
real charm of Ishq-e-Mamnu, how a party boy, a Casanova falls in love
with a girl and his life changes completely, he goes crazy for her. He
loses interest in things that he earlier used to enjoy and that girl is
all he thinks about anymore. She becomes his life and the playboy turns
into a passionate lover. The guy who never took any relationship
seriously, for the first time in his life, felt just love for a girl.
Bashir threatens Behlul that he will reveal it
to Adnan if he hurts Nihal in any way. Eventually, Behlul convinces
Bashir to give him the CD he made, without knowing that Bashir still had a
copy of it in the computer and broke it. June comes so the wedding day comes too. Nihal is getting ready with
her make-up artist and hair stylist. Bihter is home, suffering alone,
locked in her room. Firdevs gets worried and manages to enter the room
through the bathroom door. She tells her daughter to keep her head up,
because she is stronger than anyone else. At the very moment, their would be no eye left tearless, she was crying hardly, as it was difficult for her to survive the loss, the very loss of his love. She bids her last good bye to her mom, kissing Firdous on her cheeks and telling her to leave for she is gonna reveal all the truth.

Later, Adnan meets Deniz de Courton at the cemetary and she tells him
that something happened behind his back. Coming home, Adnan visits Bashir
who was resting (he was suffering of pulmonary cancer in terminal
stage). Bashir tells Adnan the truth, wanting to die in peace. Bihter then takes her last bath and wears her white dress. She was looking damn really pretty , like a doll, free of sin, like a sad doll.
Behlul comes rushing into Bihter’s room, called by Firdevs who told
him that Bihter is ready to reveal everything to everyone. But Bihter
has a gun in her hand and threatens to kill herself. She wants Behlul to
choose between her and Nihal. He starts crying, begging her to put the
gun down.
Firdevs is running away. Nihal comes by, dressed in a wedding dress,
alarmed by the phone call she received from Bihter. She catches Firdevs
on the stairs and asks her what is going on. But Firdevs is crying and
doesn’t say anything to the girl.Adnan
is horrified by the truth he found out and runs into house to figure
everything out with Bihter. He bursts through the door and finds Behlul
there, crying in front of Bihter. Then he sees the gun in his wife’s
hand. Bihter pulls the trigger.

AND in this way their love full of lust and cowardice, their forbidden love, comes to it's end and even it need to be, when ever you follow your inner desires, ignoring the terrible realities, the disasters, it would always have pathetic, the most horrible ending. Like in case of Bihter and Behlul. Behlul then leaves the home heartbroken, and cries for the rest of his life for his Love Bihter , innocent cousin Nihal and dad like uncle. He accepts his cowardice that he was coward enough to hold Bihter's hand to accept his love before the whole world, he accepts how much he has loved her and only her, but now it was useless, he has lost her forever and now he has to live with his guilt, guilt of cheating, guilt of murdering.
Some of their Moments:
Yes it was, but of another way!
They've loved each other loads, but the consequences were never with them, first of all they were aunt and nephew in law, then Behlul's cowardice for not holding on Bihter's hand and then Mrs Firdous wicked plan.
- But where was Love between them?
