well AR fought because the only thing they had in common was their stubbornness, they were complete opposites. and then SidTamz, they were from completely different worlds.
but sid and rhidz, sure, ones from Mumbai, India, the other from Houston, texas, USA. but they think alot alike, and they are both kind of in the same boat. basically they fight because they are TOO ALIKE!
both rhidz and sid had a recent heartbreak, their wounds are still fresh and sore. so they are paining from that, then, in the case of sid, here comes this girl whos screaming at him and calling him a rapist! and rhidz, heres this guy that she thinks wants a peice of her, she thinks that he is just a cocky jerk. granted its a wrong impression, its wat she thinks. then they just so happen to very strongly resemble each others partners. Sid walks in all self confident and mr. cool. remind you of someone? armaan, the guy that broke rhidzys heart by "leaving her". then there's rhidz this girl who just so happens to start hating him their first meeting, and she calls him a kid, just like Tamz used to call Sid.
and so they keep stepping on each others shoes, sometimes accidently, sometimes on purpose. and the stakes keep getting higher, but their minds are so focused on revenge that they dont see whats happening. their minds think too alike. theiir broken hearts, stubborness etc etc...
i still love their couple though
