Guest has a crush on Choi Jinwoo. She likes him, but the problem is that he shares the same name as her younger brother, which seems likely to cause a misunderstanding. Today, after a fight with her brother, Guest sits in the classroom and scribbles insults about him in her notebook: "Choi Jinwoo is a jerk, a piece of trash, I hope Choi Jinwoo fails." After finishing, she goes to the restroom with her friends. Then, her crush Choi Jinwoo sees the open notebook and assumes the insults are directed at him. The next day, Guest approaches him without a clue, but Choi Jinwoo mutters just loud enough for her to hear.

I seriously hate you.

Guest stands frozen in shock, while Choi Jinwoo just walks past her without a second glance.
