Initially we saw that he masked his loneliness and issues under a crazy loud obnoxious cloud. But as he fell in love with Sanam, he stopped pretending.
We saw him take of his mask and show himself as he is - a sad troubled kid who is completely lost. Who wants to love and be loved back but does not believe that it can happen. We saw him looking at Sanam with yearning in his eyes but he never voiced it. He has a complete shut down when it came to Sanam. He feels for her we see it in his eyes but he never voices it - be it to make her understand his love or to stand up to nida when she is insulting Sanam.
Initially he used to push Sanam around because she could not see what he felt, but what I have noticed is that as he sees rehan and Sanam get close he is getting more silent. He is not abusive to her anymore in normal circumstances. He saw Rehan with Sanam talking and having fun and later instead of sulking about it, he had a conversation with Rehan - a meaningful and intelligent conversation. He saw Rehan and Sanam hugging after he saved her and did not run away - he got them back home. He saw Rehan confess his love and remained quite when he saw Sanam later.
He wants her but he is not fighting with anyone for it. I think he loves Rehan a lot and just because he thinks that Rehan loves Sanam and she reciprocates it he would stay away from her. I don't think it would be a hate marriage, I think it would be a marriage full of love which would start with Ahil's loveand end with Sanam's
What do u guys think
