Prediction! Why Ayaan left ??

Hello,
First of all, assuming the fact that Rishabh
Left the show and until they find the replacement
CV's have shown that Ayan is left.

Possible reasons for his leaving the house
Which I think might be:

He must have seen the footage of a recording
Where Razia put BM stuff in Zoya's thaal and how
She instigated the entire drama.
Ayan knows that Razia is an evil woman who
can go to any extreame extent for her motives.
He has witnessed her hold over his father and he knows
one thing for sure that Razia is not going to stop blackmailing
even after he is married to Humeira. She has the capability
to make his life miserable by always blackmailing him with Rashid.

Ayan wanted his brother to be a part of his sagai, and he knew that Asad is seeing
the function live . He is saddened/ hurt and angry by the fact how Razia insulted
Dilshaad in front of everyone. Ayan knows
Dilshaad's place in Asad's life and he can understand what Asad might be feeling
when he is hearing and witnessing his ammi's insults.
Somewhere, Ayan feels responsible for this that he wanted Asad to be a part of sagai and all
the pain that Asad and his family has to suffer is indirectly
because of him. What was Asad and his mom's fault that they had to suffer this humiliation ?

Ayan always appreciated zoya's efforts to
reunite these brothers from the beginning .
Later he became good friend of her. Because of his
wish, Zoya came to his sagai so that Asad can see Ayan 's sagai.
After doing so many things, his good friend Mona darling
has to witness so many insults , wrong accusation of giving Humeira poison and thappad from
Razia. What is Zoya's fault when she was just trying to bring some happiness in Ayan/ Asad's life?

Ayan was feeling guilty for Humeira as well.
She is Ayan's childhood friend who always loved Ayan
and always kept his happiness in mind.
Ayan cared for Humeira from the bottom of his heart, still
he never felt any love for her.
He knew that Humeira loves him a lot and is very happy with their nikah.
But he is feeling guilty that he is marrying her but in a way he is deceiving her
as he may not be able to reciprocate those feeling what Humeira is expecting .
What is Humeira's fault in this, that she has to be part of their
loveless marriage.

Lot of sadness and pain for people who he loved , he is feeling indirectly responsible for their hurt.
Ayan thought he has not become a good son as he could not free his
parents from Razia's changul and could not end their sufferings.
He has not been a good brother as he only wanted to be a part of his brother's world and their world to
be united, but whenever he tried to make it happen it always lead to a disasterous situation.
He has not been a good friend as he could not do anything for his friend who suffered so much humiliation in front of him.
He is never going to be a good lover / husband to Humeira who loved him so selflessly but how he is deceiving her making her believe that he in love with her and that is why he wants to marry her when in reality he knows the foundation of their marriage is based on deceit.( which he can not even disclose to anyone).
All this is happening is because of Razia and he has somewhat become the pawn in Razia's hand to unintentionally hurt Asad family/ Zoya and Humeira.
He is so disgusted with the existence of Razia that he is feeling suffocated and he just can not breath in the same air where Razia is. It is too much to handle for him and that is why he is leaving.

Now I think Asad/Zoya wedding, Tanveer exposed, Zoya's truth being Siddhiki's daughter and Asad/ Zoya separation ( as per original zee synopsis with Asad and Ayan name change), Zoya's entry in Siddhiki's house will happen and I think that is also when Ayan will be back.
He will be completely oblivious to the fact that Zoya is his bhabhi. And may be eventually,
he will fall for Zoya ( I am thinking it will be one sided though)

Since Ayan has left home, there will possibly more Asad/ Zoya screen time.

A wonderful prediction. I do want the original Ayan to remain in the series. Its always a pleasure to watch the team from Day 1 of the show to the end.
