After swayam found out that sharon's friend ship with kriya was fake, he started to judge her and he even said that she could do anything she wants to get what she wants. He said this in front of the gang and this really hurt sharon. So she decided to become sharon the diva again and to make swayam realize that even thought he doesn't give her importance, she is important for herself. She is now currently trying to move on from swayam. Ruhi is vp sir's neice and a new admission. She is supposedly suppose to be the third angle in swaron love story. Swayam saves her from ragging on first day of college and they become friends. Sharon is jealous so she is rude with Ruhi because she sees ruhi out with swayam on a chai "date". Now on rose day, swayam is taking ruhi as his sate and sharon is taking vicky as her sate.
Hope this helps.
