Adi is traumatized of his separation from Imlie. And now he will have to fake his care for Mun. What do you think how much flip he will do even if it's just for pretence?
I think Imlie in his house and the constant threatening that Imlie may marry someone else (Seethi marriage can be a trigger of this doubt) may lead to some actions from Adi.
I don't want to see flipper adi anymore but without that he won't be able to please mun.
Oh gosh , he knows he' is mun's jijaji. Gross seriously.
