In the Paanch ka punch segment of IF, Lee asked Kunal if he ever "line maaro on his best friends girl friend to which he replied ki "nhi lekin maine apne best friend ki behen pe lina maara hai"
Now Nakul Sahdev is a close friend of Kunal (not including PH here as I doubt he has a sister) and he is the brother of Bharti, (I am not sure if they are real siblings or Rakhee siblings, but jo bhi ho they are),
To kahin ye statement Bharti ke liye hi to nhi tha
Sochne ki baat to hai
