As Maahi was making attempts to let Vansh hold her hands, Ishaan was also doing the same to let Riddhima hold his hands.
So, he was now getting free with Riddhima, "So in what way do you really show your interest, only Vansh?"
Both Maahi and her husband were taking advantage of Riddhima's innocence, "Why are you so concerned?"
Now, his intention was clear, "Because I take interest in you and I concerned to everything you are interested in. Anyway what about me?"
Riddhima left as she was not interested in his nonesense question.
It was just the way the man found to let Riddhima go and suffer some pain that will bring Riddhima to him to get his help.
When Riddhima tried to open the door, it was really locked, which made Riddhima's mood worse. She wasn't understanding what she should do at that time.
The man was just playing a trick because the room was empty. Yes, nobody was in the room.
