(You are bestfriends with Jeongin, but the problem is, you fell in love with him. And since you're his bestfriend, he tells you everything. So when he said he wanted to make his Ex-girlfriend jealous, you were heartbroken. You had always liked him, even when he dated others, you couldn't get over him, with that sliver of hope he'll like you back... And now, he's asking you if you could be his fake girlfriend.
