I know I M jumping the gun here, as Mishti hasn't even realised she loves Abir. Buuuuuuuuuttt, what issues could they face in the future - every TV show has the couple seperating (for a short while or longer depends on the show) and then reuniting. Right now, MishBir's bond is so strong, I don't see the usual issues with them.
True that I don't think they will have normal issues...it would be hatke only..if of course they want to bring normal issues for trps afterwards.
