I get the impression that Paras is really regretting picking Mahira for the love angle rather than sana. He obviously planned the "2 girls fighting over him" theme well but it has now back fired. He is really trying hard to keep this fake showmance going with that annoying Mahira.
If paras had given sana bhau from the beginning then things could have been so much better for him in terms of the games. She would have been head over heels in love with him and she would have carried him to the end.
He must really be annoyed with his choice and completely jealous of Shuklas position. That's the position he wanted in the house.
I'm happy his plan backfired and hope he gets booted out with his fake bimbo girlfriend mahira.
