Akuma na Kuchibiru

High school student Hana Yamada finds herself in an unexpected predicament after attending a mixer where she consumes alcohol and falls ill. Just as the situation seems dire, she is rescued by an incredibly cool young man whom she naturally assumes to be a fellow student. Grateful for his help, her relief quickly turns to outrage when he abruptly asks if she is actually an elementary school student. Deeply insulted by the remark, Hana lashes out, delivering a swift kick to him before fleeing the scene in a fit of anger. The following day, still reeling from the embarrassing encounter, Hana visits her school's nurse's office. To her absolute shock, the person waiting for her inside is none other than Shuuji Kidou—the very same infuriating boy who had provoked her wrath the night before. This startling reunion sets the stage for their complicated dynamic, forcing Hana to confront the lingering tension between them as their paths unexpectedly intertwine within the halls of her school.
