Shin Ryujin, a sophomore, is romantically interested in Shin Yuna, a freshman. Since she can not confess her feelings to the girl, she expresses her feelings by making fun of and annoying her and it is her only method of getting Yuna's attention. Then, because Yuna is a socially awkward girl who despises loud people like "Ryujin," so they are more likely to become mortal enemies. They are totally opposites. Do you think their story will end with them falling in love, or will they remain enemies forever?
