When Aryamaan was surprised to see closeness of Harshad and Nyonika, then Harshad told him that this family is weird and there are a lot of secrets. I will help you with all secrets to take revenge on Manik. One secret is Nyonika Harshad mystery relationship,another is Manik's dad and what is more. I mean Harshad is aware of many more things about Manik's family. As we know he is a dumb and according to Manik if someone will instigate him, then he will blurt out truth easily. So is there any chance of Aryamaan to know secret of Harshad Nyonika relationship? Then he will use it in effective manner. But personally I don't want it, because he's in revenge mode. He can do anything like blackmailing Nandini regarding Manik's reputation. Then more messy things will be created. But somewhere cvs are going ahead to reveal large number of secrets. So fingers crossed.
