THERE is one and ONLY one REASON that purab's character turned negative is because he ha quite the show and would not come back on JJKN so by showing him the villian and sending him to jail would end his character on the show for ever...
GOT IT..😭 😭 (for purab fans) 👏 👏👏 (for amraan fans) as in the end JAssi would end up marrying armaan..and do expect it to happen anytime soon..we would take another month or so to happen ( sometime in july or early august)
