i've been thinking about it since some days already n i'm now pretty sure its mayank.
in one epi,when aryan was walking down the stairs watching everyone suspectingly, mayank walked in looking at him with sum kinda fear.😕
then when KT took sum piece of paper in her wardrobe n went to eklavya's room n was looking for sumthing, without any hesitation mayank told her its was eklavya's,(he could have just kept it there 😡)
n i just read a topic created by sarah khan who shares her observations abt yesterdays' epi n she too talks abt her doubts that it culd possibly be mayank.
i'm pretty sure its not lakshya,eklavya,nakul,manthan or joydeep n no way its abhir(he's too dumb 😆)
