Until now we have seen a very mature side of Mayank. He thinks responsibly about his duties as a son. He takes his studies sooo seriously. He has this no nonsense sort of an attitude. But ever since he has realized his feelings for Nupur he has started doing cute childish things.
1. Ordering Paneer just to show he is as good as Chironji or even better.
2. The whole "mujhe chat nahi khana" and Nupur shoves it in his mouth.
3. When he gives the taxi driver "I told you so... I won" expression.... ufffff
4. Running around the trees like little kids.
5. Hiding behind the pillar to avoid going with Nupur.
