I really don't understand why there can be any reason for Viren to turn 'psychotic'/grey or something. If anyone has to go crazy it should be SIDDHARTH! Poor guy was barely able to manage the breakup with his childhood love when he found himself married to Miss Dumb Divya Sood. And just when he had realized his responsibility towards the relationship his wife asks him to make such an extreme promise! How is he supposed to handle all these disappointments and rejections? And his wife doesn't even appreciate the fact that he's trying his best to be a good husband! 😕
Honestly Siddharth should go crazy out of jealousy on seeing Viren and Nivedita happy together. He clearly still loves Nivedita and doesn't want to see her with his brother!
