Sid has temper issues and Asim is very robotic. Arhaan and Vishal are in the house with their alleged GF's.
Paras on the other hand is chilled out, funny and not too stuck up like the other guys. He understands women emotions better and is good at understanding things which are not generally verbalised. Like he told Sid that Aarti missed him more than Sana. He is more of an extrovert unlike Sid/Asim who are better looking but very restrictive and tight in their approach.
