What's that romantic song played for Vina?

Ok so Guys what's that dheere dheere song played in the background when Rachna was making chocolate cake for Vihaan and imagined him dancing with her. And also when she was imagining him giving rose to her on Valentine. That dheere dheere song, what's the full song name and info? I wanna hear it.

Oh plus besides those two time I just mentioned, did it ever play any other time?

it's called Saibo from Shor in the city...i only remember it playing those 2 times
