Kim Chaewon has been liking her bestfriend Jang Wonyoung since high school, even though she's fully aware that the latter has been crushing on her childhood friend, Ahn Yujin. She acknowledges the fact that she doesn't have any chance on her but she can't and doesn't have any idea on how to get rid of her feelings. While in a PC Bang, that she's been going to almost everyday after finishing her classes, she notices a new face enter. It was of course normal for new faces to be seen in PC Bangs, but the unusual thing was her heart. It was beating in the same sync as when she's with her bestfriend or maybe even more active. She gets confused and later discovers that the girl she was unsure of her feelings for, was going to take part at the same camp she's supposed to ditch.
