The three girls who have a crush on high school boy Izumi Sumie are all main heroine-tier stars! The school idol, but secretly a gal who just wants to be pampered - Amane Amasaki! The pristine student council president, but a former fiancée who loves to dote on him behind the scenes - Hakua Shiragiku! The bratty kouhai, but a surprisingly easy-to-win-over little devil - Haru Kasuga! However, perhaps because their positions are so rock-solid, they have spent their days unable to take that next step forward. Then here comes the transfer student, Nanao Nanase, a seemingly ordinary but naturally born main heroine. A single sentence from her instantly rewrites the balance of power in this rom-com!
