Yeah, she will not turn negative. I think she'll be surprised that she is jealous of Trish-Yuv, and will dig deep in herself to figure out why. It's at that point she will realize she is in love with Yuv. Yuv will of course notice this, and you'll have that scene you've wanted: they have an argument, confess, voila your new couple. Vah, kya love story hain.
This is so repetitive, that I'm half-awake now and can still write it. Would it have just killed the creatives to do something different and not alienating. This storyline and romance is STUPID!
