For MP because of how Arjun kept taunting her by saying that she'll always be alone. And that ever after graduation, she'll be back to where she was because everyone will move on in life after graduation. The part that really touched me was when MP says that they won't go away because she'll follow them. I felt so bad for here there.
Then, when she thought she knew her gaurdian, she finds out that he was just appointed by Arjun. So there again, she was decieved and heartbroken. The one thing that she wanted to know, she thought she knew it, only to find out that it was just fake. =(
For Nakul, because how in todays epi he was like, he wants to be cool but whenever he tries it turns out to be uncool. Then the whole crying scene that he had in today's epi just got to me. The whole saying how he was feeling low and didn't feel like being in his apartment and all. *tears up*
But then again, Nakul's issues sorta got solved out in the epi, but MP's didn't. She even had to face Varun again. =( Where she even goes that she just doesn't want to be his friend. *tears up* Man, I feel really bad for MP in today's epi.
