she is jealous and deliberately avoided Gu Xun. he can't help kiss and punish her. 

wtf do u even watch the series, he rejected her because he already has a crush on another girl who he play games with online without even seeing her face, thats why he reject her and the mic was on by mistake, but turns out the girl he rejected was his online crush. thats why he wants to clear the misunderstanding but she never gave him a chance to explain himself, and there was also a misunderstand cause she switch account with her cousin. IF it was the girl who did the rejection, u wouldnt have a problem, IF U R THIS SENSITIVE DONT WATCH DRAMAS, GO WATCH SOME CARTOONS

Hey, first watch the whole drama then you'll understand!!

He had a crush on another girl which ended out being her, but he didn’t know it was her. So no he wasn’t being a jerk he was just being loyal to whoever he liked.

Tf you talking about did you even watch series or not. Okay understand it by an example ~ you like a girl or you talk her with all the time but you don't know her face at all (understand this point), or then suddenly a random girl proposed you in front of a lot people so would you accept her while you already have crush on the girl, who you talk with all the time. Or the girl who's proposing you is actually the girl who you talk with all the time, but you don't know her face. That's why you rejected her. So tell me now how is this his fault, or then in the next episode he come to know the girl is his crush. That's why he's approaching her. Please watch dramas with some understanding if you can.
