on holi day there was a dialogue jo mujhe rangne aate hain woh mere rang mein khud rang jate hain then mishti responded mein tumhe apne rang mein rang doongi
so from above dialogue the person on which colour fall will fall in love with the person who coloured him
so today abir accidently coloured mishti hand with red colour by that logic mishti will fall for abir
and mishti wanted to throw colour on abir but it accidently got into kunal so by that logic kunal is going to be coloured in mishti colour or fall in love with her
i think kunal will fall for mishti due to mu the thing she will do for abir kunal will consider it for himself due to some twisted mu
later kunal and kuhu will fall because both will go through the pain of rejection and this pain will connect them
