she's already seen him act cute over a certain girl on the network. and she is a hard core romantic. help her tease him Zhong, and then quietly push these two lovebirds together.

he's basically her canon brother, just toned down a little. but yes, he's one of those brothers XD she'll be so surprised at first that Zhong knows what she looks like, and then realize she shouldn't have been surprised at all. b/c big brother.
