After transferring to Kirisawa High School, Hina Tsukimori slowly becomes isolated by rumors and silent bullying no one wants to acknowledge. Ren Kazami notices the change because he has seen the same pain before — in his younger sister. What begins as simple concern gradually turns into something deeper, as two lonely people slowly become part of each other’s everyday lives. A quiet and emotional story about healing, friendship, and learning how to live again after being hurt.
