During the first three years of his new life, Reesha attended school with his former subjects, now counted as his closest friends. However, once his comrades graduated, they enlisted in the military, leaving Reesha behind due to his artificial heart and diminutive stature. At 19 years of age, Reesha now lives as an ordinary plumber in a town known for its thermal springs. In a desperate attempt to overcome his physical limitations and join his friends in the army, Reesha and his allies devise a plan to meet with the general directly by sneaking into a bathhouse. Alas, this daring plot leads to unforeseen violence and upheaval, prompting Reesha to abandon his mundane existence and embrace his fate with newfound determination!
