The Billionaire Father-in-Law's Revenge [Tamil]

Ruhi traps a rich heir, pretending to be innocent while secretly cheating on him. When she humiliates an old man at a car showroom—beating him, insulting him, and burning his wife’s last photograph—she doesn’t realize he is Rajat Singhania, the billionaire founder and her fiancé’s father. Now the insulted tycoon plans a brutal revenge, determined to expose her truth and destroy her in front of the entire city.
