Meticulous first‑year student Akira Kagiura has shared a dorm with senior Taiga Hirano for six months. At the start, Kagiura worried about adapting to campus life and felt uneasy in the new environment. Hirano"s energetic presence, constant support, and friendly advice gradually eased his nerves, allowing Kagiura to feel content and at ease. Each day he relies more on Hirano"s guidance, and his admiration for the selfless roommate deepens into a strong affection. With only half a year left together, Kagiura is determined to give their bond a name before it ends, for a lifetime always.
