@4sarah1212 No he didn't. If I'm reading this right, the ML just took the card because he was in a hurry then the other guy who's always with him (I've forgotten his name, sorry) was curious about this "gift" and asked for the card to go check out the girl that was being offered (I have to say I'm kinda disappointed in him), then when he found out who it was he called the ML and waited outside the room, which is why he's insisting that he didn't see anything. CEO Zhuo was probably hoping that if he could get the girl the ML seemed interested in at the party for him, the ML would stop putting pressure on the CEO's company in revenge.
edit:
@4sarah1212 again lol. Oh good, I thought the transition between the pool scene and the hotel was confusing myself, so explaining it kind of helped me clear it up too^^. And yeah the Zhu guy is out of his mind clearly (I mean leaving out that the ML will destroy him, doing stuff like that is messed up)
