Hong Xiaochen managed to quell her rage somewhat and roughly guessed in her heart, estimating that Senior Brother Wang must have confirmed that she and Chu Nan were boyfriend and girlfriend, which is why he let his guard down around him and handed over the room key directly when he saw him.
But even if that was the case, Chu Nan shouldn't have just used the room card to really come in. Even if he wanted to make an appearance, at the very least, he should have called first, right? How could he casually enter a girl's room?!
"You sure have a lot of questions," Chu Nan said with a frown, speaking irritably, "I came here to have fun with my girlfriend. Why the hell would I need your room card? Besides, that Wang guy clearly doesn't like me, so why would he give me your room card? He'd be dying to come to your room himself! Can't you figure that out? You really don't have much of a brain."
