While shelving books in the library, working out during club time, or locking eyes in the hallway—love arrived without warning. A fresh, flirty love story between girls. Yeonjin & Jiyoon: the popular, oblivious “top”; the wounded-but-devoted, single-minded “bottom” Library club member Jiyoon is flustered when school heartthrob Yeonjin comes all the way to the library to chat and soon grows closer to her. Moved by the way Yeonjin treats her differently from everyone else, Jiyoon starts to like her and becomes convinced the feeling is mutual. But then she learns Yeonjin is actually her older sister’s tutoring student—and is nursing a crush on the sister, not on Jiyoon.
