He honestly asked her if she would be willing to come to Toronto. He was open-minded in the sense that he protected her earlier in the show, but did not treat Rakhi like his property when Luv gave her a kiss. Manmohan kind of overreacted on that one. But Manas was just being sweet.
I think he also doesn't seem to have any hang ups with Rakhi. He admitted that the only thing he knew about her first was how the media showed her as tough, but the more he got to know her, he was genuinely impressed. I see something in his eyes for her, and I think he gets kind of subdued and quiet around her. Not because he isn't confident (I think he knows how to have fun!) but out of respect for Rakhi.
I really hope Rakhi spends more time with him, and goes on at least one more date with him to get to know him. Even if she doesn't choose him, I hope she gives him a chance and gets to know him first.
