Due to a difficulty with words that often leads to misunderstandings, Chigusa has built emotional walls around herself and keeps others at a distance. She spends her school days alone, until a strikingly beautiful transfer student arrives. To her shock, it is Iroha, the only person she ever considered a friend during childhood. Iroha announces that he transferred schools specifically to see her again. He effortlessly slips past the barriers Chigusa has erected and steadily closes the gap between them. His affection runs deep, bordering on obsessive possessiveness, while Chigusa struggles with her own loneliness and the weight of her family situation. As the two grow closer, Iroha’s intense fixation clashes with Chigusa’s desire for independence, and each must confront the darker emotions stirring within. Their relationship takes shape against the everyday backdrop of high school life, moving through moments of warmth, jealousy, and gradual self-discovery.
