I am sorry but I think that her comments were not needed. He was thanking her and she just shut him down.
I agree that Rithvik has been an idiot by not saying what he felt and saying the kiss didn't mean anything. But how much can he take before he is going to blow? Wouldn't Palak have done the same thing? Let's put the shoe on the other foot...let's say she loves Rithvik and she kissed him...which she does and did. And Manjeet said her marriage means a lot her family. Would she have gone to her groom to be and said, "I kissed Rithvik and I love him"? Rithvik doesn't even know she loves him. She didn't even tell Setu when she asked Palak what was wrong.
Doesn't love work both ways? When he said the kiss didn't mean anything, why did she have to say it didn't mean anything to her? She could have walked away!! Why is it all about ego with us humans?? If she walked away I think Rithvik would've gotten a different message and he would not been such an ass!!
Just my POV.
