The scene b4 Pehlaa Pehlaa Pyar hai. Hum Dil De chuke sanam , when ashwarya walks on the bridge and asks ajay devgan to open her hands n when he opens it was a mangalsutra. The one in Tum-Bin the whole movie is awesome with lot of romantic scenes. DDLJ when Kajol asks SRK to come to her wedding and he says no thats when she realizes she loves him. Silsila the song, yeh kahan aa gaye hum In Pyar toh hona hi tha when Kajol falls in Love with Ajay n can't tell him. DTPH the lost earing scene Mohobatein the song humko humein se chura lo .........the list is long:D
