Namely, Ram follows what he sees from his sister. That is, in fact, everything is almost fine with him. Except for too much vehemence, which offended Priya, Akki and Mira ma. But this is all solely from his feelings for all these people. He loves very much and will understand his mistake.
But Shivina ... If Priya had been in her place, she would hav blown up the whole world for her husband. And which of the four married not for love, huh? Shivi urgently needs to grow up and open her soul, for real.
As for Mayatri, alas, her marriage initially hinted to me that something was wrong with her. Marry an ex-sister who acted like... Either she has a wormhole or she's very stupid. Obviously.
