A man named Kaito Sickino takes in four orphaned sisters after attending a relative's funeral. He later remembers his past life and recognizes that he is in a game world. He understands that if the story follows its original path, the sisters—Chiharu, Chinatsu, Chiaki, and Chifuyu—will face a bleak future. Determined to change this, Kaito resolves to help them find happiness. As they live together, the time spent with Kaito gradually heals their emotional wounds. His kind and genuine words help each of the sisters, who have distinct personalities, to open up and feel more at ease.
