Tere dil ke nikaale hum Kahaan bhatke, kahaan pahunche

At their Vila when lax reached...
The atmosphere... How shanskar left them alone and sat in the corner...were they waiting for lax to come...
Or they decided at that time...

When lax on sitting on his car...
I remembered this song

Tere dil ke nikaale hum
Kahaan bhatke, kahaan pahunche
Magar bhatke toh yaad aaya
Bhatakna bhi zaroori tha
Mohabbat bhi zaroori thi
Bichhadna bhi zaroori tha
Zaroori tha ki
Hum dono tawaaf-e-aarzoo karte
Magar phir aarzu'on ka
Bikharna bhi zaroori tha
Teri aankhon ke dariya ka
Utarna bhi zaroori tha
