can it be only possible that the letter that maj bhargav hid in naina's cupboard be only from rajveer to naina?
or why can't it be a letter from navin to his gf ...which maj bhargav has intentionally written(thru ali) in navin's handwriting and hidden it to make it look like someone is helping out naina to know about her bro? maybe in the letter, navin must have confessed that he has done something wrong ...if it is so then naina will have to admit that navin is a traitor after reading it.
but then another question crops up...why to take the pain of sending rajveer and naina together?😕
