I mean even if Ishaan is TRULY sorry and has changed, How long will it last? I mean come on, This is Ishaan. I doubt he is going to be the same after they get married, I can already see the sweet lovey-dovey act dropping after a week of their marriage because Ishaan and Mahi are very different people.
He is like (over-) confident hot shot of some sort while Mahi is like simple and just normal girl so I see Mahi having to, like, change herself for him (The scene with Mahi's sis doubting about her and Ishaan then the end scene with Shiv in the golgappa place where Mahi is thinking Ishaan would NEVER come here) and will that make her happy?
She would like need to act like Mrs.Ishaan Singh Alluwahlia's wife and I think Ishaan would get mad if she doesn't portray herself correctly which would obviously end up making Mahi unhappy in the end.
I mean, from what I have seen till now, Ishaan can be understanding for a while but afterwards I doubt he will be able to be understanding at all.
I'm not saying this as a Shiv fan or anything since I don't even hate Ishaan THAT much but just looking at both of them, it just shows how miss-matched they are.
