i just watched a bit and here is what happened...
I think ayushman has to take bodhi out of his friends house...so i think tani's sister (doctor) asks them to stay in her place. Bodhi and ayushman go there to stay. Ayushman I think leaves his house. Hid dad thinks he will come back...but ayush is not. His mom and ayush seems to be not talking to his dad.
Dadi, ayush, bodhi go to live in tani's house and sonia is not happy about it. She tells ayush to be careful and not ask any favor from tani. Tani watching ayush and sonia and misunderstands and thinks that they both are getting married...she is staring at them with jealously and think to herself that she loves ayush and she will try to get him till her last breath...
