Sticking my neck out here. Suman comes across as one too eager to get back with her childhood pal. Glossing over the way she treated him as a teen. As someone posted on the main forum the other day... would she have been as eager had he been a plain Joe?
Taking a real world view... Mr Invisible is now Mr Popular. Take the love story out of equation... any guy would doubt the change of behavior. As for the public humiliation... desi show after all. Plus the whole 'bhagoda' thing pricked him big time.
And of course, they need to get the 'Pyaar aur sammaan ke alag alag hain raste' equation in.
