Kunj never felt jealous of Yuvi.He showed is protective nature n his authority on Twinkle.When Yuvraj tried to touch or harm Twinkle.He said how dare you touch my wife.
So I also feel male friend of Twinkle is best option to bring hidden feelings of Kunj.He doing things out of his character would be treat to watch.
Ya Kunj was so confident only he can handle Twinkle's craziness.Twinkle male friend should be crazy as her.Then would be worth watching.Kunj reacting Twinkle be friendly with a guy.Who can handle her.
