Haite Kudasai, Takamine-san

Takane Takamine is a high school student council president admired for her academic excellence, athletic ability, and striking appearance. Koushi Shirota, an average student with few social connections, becomes aware of a hidden aspect of her life—her underwear, which allows her to reverse past actions when she removes it. After discovering this secret, Takamine takes measures to ensure Shirota does not reveal it.
