Yui, a man working as a permanent part-timer, stumbles upon an exhausted stranger collapsed on the street. Despite the man’s worn-out state, Yui is captivated by his strange charm and finds himself unable to simply walk away. He helps the mysterious Toshiki back to his residence, gradually lowering his guard and allowing himself to be drawn in by Toshiki’s subtle manipulations. What begins as a simple act of kindness quickly shifts into something far more complex as Yui willingly accepts Toshiki's influence over him. However, the situation takes a dark turn the following morning. When Yui wakes up, he realizes the doors are locked and escape is impossible. With a disarming smile, Toshiki casually reveals that keeping someone confined is simply his hobby. Trapped inside, Yui is left questioning the true nature of his predicament—whether he is merely a captive or something more to this enigmatic man. Their delicate and emotionally charged relationship unfolds within the narrow confines of their shared space, blurring the fragile line between ordinary romance and unsettling obsession.
