Oh..der are soo many,Bhabo is a rcokstar when it comes to this department.But i'll start with my fav SurYa dialogues.
The entire confession dialogue of Suraj.It's by far the most sweet and pure confession I've ever heard.
Suraj explaining to Sandhya about Diya aur Baati when she goes to light up his dukaan during diwali.
Suraj explaining to Bhabo about love after all the gadda-palang drama
Suraj confessing to Sandy near MKG's statue that "maine kisiko us nazar nahi dehka hai aapko chodke"
My all time fav dialogue comes from Sandy - "Kisne kaha ki aap mere saath nahi the" yeah after the trophy winning.
Another one from Sandy -- "Kise pata tha ki wo anjaan aadmi ek din apna ban jaayega"
