Gym Huduga Billionaire

Billionaire gym trainer Raj saves Sukanya's sister, then helps wheelchair-bound Sukanya walk again. He falls for her and proposes at her humiliating engagement party when her corrupt ex and greedy father betray her. He later reveals he's actually Lord Titan — a 50,000 crore empire owner — destroys the villains, and wins Sukanya, who loved the "gym trainer" all along.
