Virat when he thought he loves pakhi
Mesmerized by sai, wanted her attention, gets jealous of other guys for her, flirts with her, wanted sai to behave as his wife,wanted to spend time with her.
Sai when she thought she doesn't love virat
Forgives virat for his abuse, gives in to virat romantic advances, playfully flirts with him, enjoy spending time with him.
But don't want to see this relationship beyond deal/ friendship. Virat needed sunny to make him realise what he has for sai is love. Virat don't have any barriers or insecurities, he is free to love sai but sai isn't. On her marriage day itself sai is told by her husband to not expect anything from him. Throughout the year she saw her husband & his equation with his ex. She saw his ex claiming rights on her husband. She saw her husband not stopping his ex from crossing lines (most of the times). And she saw how abusive her husband gets when things don't get well between them.
Now she got a chance to have peaceful life with this friendship phase. No barriers,no responsibilities,no insecurities now. No fear of getting into fight, no fear of getting questioned as wife. She is happy with this platonic bond right now. Many people who were in love for years would be scared for marriage. Whereas sai saw what she had to go through in her marriage phase. Now she don't want to go back to that atleast not soon. She wants to have her own time. Don't want to think her relationship with virat as romantic one. If virat makes romantic moves towards her she won't resist because of her unrealised feelings for him, but if virat won't make romantic moves towards her she would be absolutely okay (in this phase) as what all she wants from this relationship is friendship not more than that.
Virat's unrealised feelings towards sai (when he thought he loved other woman & giving explanation to other woman) is cute
Whereas sai unrealised feelings towards virat (when she thinks she doesn't love him or he loves other woman) is irritating?
I took this comparision in order to know the difference between two. About physical proximity, virat & sai on their first night itself got physical unknowingly & virat got lost in her when both don't love each other. Why can't both think whatever close moments they share is just attraction which normally people do going with the flow. Otherwise virat would have wondered by this time that why would sai recipocrates his romantic moves if she doesn't love him.
If it's about sai not getting virat hints then he needs to be consistent. Sai already proved wrong by giving into virat's hints where pool side confrontation of virat pakhi gave her reality check. She don't want to face that again.
