Sai: Extrovert, happy go lucky girl who doesn't keep anything inside...she just conveys all her feelings, happy, sad, disgusted everything. Actually, it is necessary to say out loud, that thing does remain in your head to play with your feelings and emotions, hence she doesn't have anything as such negative for anyone, not even for Pakhi didi (so far, after leap, has to be seen). She was perfect the way she was for her aaba, didn't have to prove anything to anyone, she had that confidence. Sai's little me is Savi.
Virat: that Mahaan image, the perfect Chavan beta, needs alot of patience to keep things inside him, he has to be mature, think twice before speaking, so can't speak or when he does, it's too late to make amends. And the things keep increasing inside him, to their threshold, after which he cannot take it anymore and bursts off. A typical introvert, ideal kid who turned out to be an adult trying to get accolades from his family, especially his father to tell him that he is proud of him. Virat lacked that confidence, for the need to appreciation in an abusive household. Virat's little me is Vinu.
People like him, need someone to vent out those feeling, that someone who can understand them, love them and not judge them, who make them feel loved, important, for Virat, that someone is Sai, so all his gussa is reserved for her. He understands everyone but Sai needs to understand him. He is not everyone/ anyone's priority, so he should be Sai's, when he is not, his fury meets no ends. Sai gave him that confidence, that freedom to be himself, the reason he fell in love with her...if his love is reserved for her, so does his anger too...
PS: not justifying him and his abuse, just a thought came to my mind, expressing it. Also he married Patralekha, i hope that they give some solid backstory, however, it might be due to family 's extreme pressure and him again being that submissive one, took their order/ suggestion because he might have been made to realise that how he was wrong in marrying Sai who killed their 'chirag' and how Patralekha was perfect who was such a Mahaan surrogate, to give birth to the child. Again, him not being expressive with anyone, not even Ashwini, gave in, again to make his family happy.
