i actually read an article on tellychakkar that MK's dad will be played by an actor called deepak dutta, and he will want his daughter married to a rich family...
Here is what I think: shashwat has two reasons for stealing jewelry and stopping his mom. a) he want's to marry MK and give the jewelry to her, and b) stop Anijal from getting jewelry and ashirwad.
i think there is something fishy about MK and her father.
