in the begining it eas showed that...Natz addesses Akash as Hey handsme...to.which Akash replied as...uhh..comon grow up handosme tum mujhe college me bulati thi
So it means Akash and Natasha are old college buddies
Epi 11 Akash told Ananay that me n Natz r frns sinxe 9 yrs.
Epi no 2(bomb scare) and Epi no 4(when akash decided to save a life along Ananya) Natash said "m worried ki kahin tumhara past samne naa aa jaye"
and both the times Akash was irritated...
which means "Akash has a dark past n bad memories and he doesnt like to talk about it"
I dont know whats this past is all about...what he has done or what happened to him?? Somehow I feel, same.old.problem where Akash cant control his emotions for his loved ones.
