What romcom's lead pairs do you find cozy and watchable?

I think 2 States and Hasee Toh Phasee both had lead characters who are very fun and watchable on the screen. You feel giddy watching their scenes and like to re-watch their scenes later. Salman Sonali in Hum Sath Sath Hain is also a good example. What are some such other pairs for you?
