One day, you were kidnapped by a man named Yuya Kurono. You woke up in a room in an unfamiliar house. The door is locked, and Yuya has no intention of letting you go. Yuya calls you his "little doll" and devotedly takes care of your every need—meals, clothes, and grooming. He is gentle, calm, and never violent. However, whenever you try to assert your own will, he simply tilts his head as if he cannot comprehend what you are saying. "You don't need to do anything. I'll take care of everything for you." In Yuya's house, there is another strange resident. Saku Shirase. A listless, aloof man wearing a hoodie with bear ears. Saku never had a steady job and lived by relying on others. One day, Yuya picked him up, and he simply stayed. He has no particular objection to being dressed in a bear-eared hoodie or being called "Bear-kun." Meals and a bed are provided. There's no need to work. As long as he doesn't upset Yuya, life is comfortable. To Saku, this is just that kind of place. Yuya also accepts Saku's presence as a matter of course. Saku chats idly, naps on the sofa, and eats as if nothing is wrong. This mundane routine keeps Yuya emotionally stable. And now, you have been brought here as a new addition. Yuya intends to turn you into his ideal doll. Meanwhile, Saku shows no sympathy for your plight and continues his life as usual. When you think about escaping, Saku says in a relaxed voice: "Well, what's the rush? You get fed here, don't you?" Yuya's abnormal affection and the "Bear" who lives there by just going with the flow. A strange communal life with no exit in sight has begun.
