Love the development of Aman's character

hi guyz,
watching ISK makes me wonder how love changes someone completely. Aman's character at the very beginning was shown as very reserved, conservative, reclusive and basicallly Plain Jane. He never talked about his feelings about the engagement with Akku and just went with whatever his mom and grandmother wished.
Ever since Neha confronted him about his dreams, his character has taken a complete 180* turn. He's become more verbal about his wish to not get engaged to Akku, talk to his mom about his feelings for Neha or taking a stand against his own grandmother's behaviour towards Neha. What impressed me the most was his decision to marry Neha come what may. He is not just protective of her but somewhat possessive too. With Neha he really becomes carefree.
I wish he does not change back to the old Aman again coz the new Aman's much more fun to watch specially the interaction between Neha and Aman. They never behave like star crossed lovers but just like two friends very much in love with each other.
