I do think Vishwa does know at least part of contract marriage truth. But here is the thing na - The marriage is legal by all means. The fact that these 2 intend to go their separate ways is known only to them and now maybe Vishwa too. But what is the guarantee that Imlie will marry Vishwa ? Or for that matter Vishwa will be able to make Imlie fall in love with him ? He has himself seen how possessive Agastya is for Imlie and how Imlie stands up for the family. Even if they go their separate ways there is no way Agastya is going to get another wife and neither is Imlie going to move on from Agastya. So I don't know why Vishwa keeps on making gooey eyes whenever he sees Imlie. Plus the actor seriously lacks any charm and I feel like closing my eyes when he is on screen. Sigh.
