I intended to write this but I didn't have much time to do it so here we go , when I go back to S1 and remember how Karaca was , how insecure she was , how she felt as the " less Kocovali " granddaughter, when I remember how she just wanted Celasun..
Only to prove to herself that she is worthy of someone's love, with Clsn she always had to beg for attention, throw herself to the extreme( once getting shot and once falling for that trap of Aksin) just to be noticed by him, being herself was never enough
And in the end he chose Aksin over her , she was never his first choice. In S2 , they both survived a traumatic event , yet Karaca knew how to grow and learn from her mistakes, she tried to redeem herself in every way possible. What did Clsn do ?
He became an emotional leech, he just wanted her be there for him , he confused her, it was okay for him to go to her without any defined relationship on the pretext that he sees Aksin as a kid now ! He wanted to walk away from his mentally unstable wife
He was just standing in karaca's way towards breaking free from her old self , he was her test , she had a chance with him and she maturely refused it because she would never hurt Aksin , she'd rather live alone than to see Aksin unhappy.
In S3 Karaca was completely different she was the epitome of Cukur , protecting that place whatever the cost was , we didn't see much of Clsn with her , he nearly called her once while he was remembering Aksin! When he knew about her relationship with Azer
Instead of going directly and talk to her, he went to ymac ! In the name of every bit of unconditional support she showed when no one cared about him, she owed him at least this, he had no right of going behind her back and invade her privacy the way he did
And then he obediently accepted that arranged marriage , you would say he wanted to protect her , no there is no protection that comes above a person's free will. This season, Karaca went through hell , she could use a good friend...
But another romantic ship ! With Celsn in particular and after all their history ! And after all the development she had in the previous seasons ! It just doesn't make any sense for me ....
