if Kunal does not get his memory back he may do a few things...he may get to know about his past from one of the characters..but as he does not remember he has no fatherly feelings for pari.also he may come to know about Mauhaan and how badly he treated Mauli. So Kunal will get out of the way and let Mauhaan marry ..he also heard nAndus cd so he'll ask Mauli to look after pari as he can't since he can't remember being her father ..So Kunal will do the sacrifices and also redeem himself in the process...no pari will stay with kunal only he is her buddy.Why would she stay with mishaali.
