maya is trying to get saanjh out of the way only because she thinks there is a scope of love between arjun and saanjh. She doesnt know that arjun only thinks of saanjh as a friend.
She is only trying to hurt saanjh because she feels arjun cant love saanjh
But in the first place she doesnt know that arjun doesnt have that place in his heart for saanjh.
Maya is misunderstanding arjun and saanjhs relationship to be love because she hasnt ever experienced friendship. She thinks feelings towards someone is considered only love. Meanwhile there is a huge difference between love and friendship.
If arjun felt love towards saanjh he wouldve felt atleast a little bit jealous when saanj went to meet that boy but he didnt. Which is another reason why i feel that the romance will ultimately be between maya and arjun only.
