Ishu is not J. She is hurt. Very hurt. Because Raman is hiding something from her and meeting Shagun secretly. That's what she told Bala too. That she has never stopped Raman from being in contact with Adi or Shagun. But the fact that he is keeping stuff from her, that is bothering her.
Introducing Subbu in the story, and showing Raman jealous won't help. And I don't think that's the right thing to happen right now.
Pls give your POV people.
~Thanks.
