May be Amey is also affected but he did not show it. I remember Amey cried when Yashshree, Neha, and Panna left, but he did not show any expressions during Meenal's exit. When Meenal hugged him he was a little uncomfortable. May be because Meenal said in valentine's day episode that Amey ji was sabse hot guy in all the contestants which made him feel uneasy.
Least : Sandeep, Anuj. They are never affected by anyone's exit. I can understand Anuj because he joined late in galas and he may not having a good bonding with the contestants, but Sandeep has been there from the beginning and he is always happy that he is saved.
