Raghav and Amma, letting their anger blind them again. I understand why, but people like Sunny are successful because he sees the weaknesses or sore spots and exploits them.
I don't know why Raghav isn't more careful at home around Sunny. He should stop getting angry with Sunny and focus on Keerti.
Also, the more the Raos shun Sunny, the more it triggers Keerti to try to force this relationship on them and makes her more adamant. She won't see reason, but I hope mother and son do soon.
