Managing director Arata Sonodera is an alpha who is doing quite well for himself, but he's never forgotten Mahiro Nishina, a precious friend who disappeared from his life years ago after they spent a passionate, heat-induced night together. One day Arata unexpectantly finds Mahiro running a food truck near his company and the two wind up in bed together again, but soon afterward a phone call leaves Mahiro frantic and in tears. The two drive to a preschool and the shocking cause of the omega's distress is revealed - his sick child, who looks exactly like Arata!
