From the marriage point of view as some one who has been married for 8 years(TW 😛) i can say Rohan's temper, his lack of support towards Kittu , his lack of faith in her ..................makes him a terrible choice for a husband and happy marriage .At the drop of a hat he takes to drinking excess alcohol.
Yuvraj is a calm, even tempered guy who has faith in Kittu , loves her and always supports her and stands by her.
Another thing ........always marry a man who loves you more than you love him. Trust me these are the best ingredients for a happy marriage.
I know i may upset some Rohan fans , but believe me even if a had a sister i would advise her as some one older to go for a good natured man like Yuvraj.
This goes to all the young kunwari kuris too when you make a decision about marriage.😉
