Rono was a selfish prig … he had very exalted view about himself that what he will do is right .. he can play saviour to others .. and his wife has to obey ..
he did maintain boundaries with RK throughout.. and used to insult Rk aram se .. with shruti he was playing god .. but there never was any attraction vibes for shruti or RK ..
he was physically only attracted to emon .. even emon knew it from the start especially during the first gun shot ( hospital ) drama that Rono is attracted to her .. she knew Rono is fond of Rk as a friend , values her company .. but she knew he was attracted to her only .. and flirts with her ..
Her insecurity was more that he only wants me physically but is not in love with me .. which probably was true .. because he really did not treat her well .. or gave her priority..
Which makes virat worse ...
Virat never made her feel like that he is physically attracted to her except for few advances by him..
