REX'S behaviour

I find rex's behaviour towards rooprekha all a stunt. He wants to be put in the spot light to grab attention from viewers. He has NO feelings towards rooprekha yet since he has been labeled bunty and bubbly he has taken advantage and used rooprekha to make audience's feel that the best couple would be rooprekha and rex. Its all a stunt and he is doing it realy well. he calls her his sis.. yet he flirts with the poor girl as if he really loves her. I get this feeling that rooprekha has falllen for it to a slight extent as she is wooed by him constantly she might even have developed a crush for him.. yet rex has no feelings for her he is just using her to grab attention..
