Yuzuru, a tough-looking delinquent, asks Satomi, his senior, to officially recognize him as a younger brother as a way to thank him for helping his family during a financial crisis. Yuzuru begins to constantly accompany Satomi and take care of him, catering to his needs at all times. However, Satomi grows increasingly irritated by the constant attention, and Yuzuru refuses to back down.
