The love grown much that Vansh couldn't tolerate any boundary to be a cause of separation between them but maybe because it was Riddhima's choice, he let him go.
But it doesn't mean that he gave up because his love is true enough that his true resolution never let him to give up.
That's why Vansh let her go, but how is he controlling Riddhima's each and every action?
That person, his brother, called Riddhima to be his cohabitation, "I had given you the duty to not let her go anyway."
The difficulty was, "Then why did you set a time limit for that? She isn't going anywhere (although she left)."
He did not let her get in any doubt, "She is wise enough and she was very close to her bet also. Well, are you serious about her truly? I just offered her the three options and after that we didn't meet. Can you tell me what actually happened after that?"
