For the most part, I've been seeing the members of this forum say that they are glad that Kunal doesn't realize that Mishti is his daughter (even though this is very stupid on his part). But I have a little bit of a different perspective. I think Kunal should know that Mishti is his daughter (as I'm sure he will find out eventually) and he should know that Ishaan-Mauli are not married. If he thinks that they are married and that Mishti is his daughter, than to him his actions have no negative consequences on Mauli or Mishti because he would think that Mauli is happy after he left her. While I don't want him to pity Mauli or anything, I believe he should know the consequences of his actions. He should know that because of what he did, Mauli is having a really hard time accepting a guy as nice as Ishaan. Because of him Mishti grew up without a father for 3 years and now is under the delusion that Ishaan is her father (not that that is a bad thing for Mishti, but objectively speaking its sad that she had to search for a father in someone else because her real father was abroad making a family of his own).
