searching for a ff

pl help me find a ff/ss where lavanya understands that arnav is in luv with khushi and she leaves RM . She asks arnav and khushi to drop her in airport and when she gets a chance to talk to arnav alone she asks him to say his feelings to khushi. After saying bye to lav khushi leaves the airport in search of auto and is pulled by her hair by arnav who takes her to RM. Where is everybody is shocked to watch arnav laughing at something khushi does or says. etc etc...
