Tokimeki Bomb: Trapped with You

Six men are trapped in an abandoned warehouse with mysterious collars around their necks. Their confusion turns to shock when a plushie dog named Masao, claiming to be an AI, announces its mission: to study the human emotion of tokimeki (heart-pounding). The men must live together for several days, with the AI measuring their emotional levels. Those who fail to meet the required threshold will be eliminated.
