Shyam could be behind all of this...

Well according to the spoiler, dont know if its true or not, Sheetal is the antagonist and wants to separate Arshi as she wants to marry Arnav. But she fails. Apart from that, maybe Shyam is also behind all of this! Beacuse he's gotta get back into the storyline somehow and what do ya know, maye he found Sheetal, found out that she's Arnav's classmate, and paid her and Aarav to act like this to create an MU between Arshi! i dont know... just guessing
