Office worker Umesawa's archenemy is a very stubborn and particular man named Haze. They worked together as a team for a joint development, and yet, without a single word, Haze just quit his job, leaving Umesawa seething, unable to forget about him. On a certain night, Umesawa stopped by a bar and was flabbergasted to find Haze there. Despite his cold demeanor, Umesawa was relentless while inebriated. Yet Haze simply dismissed him, "Go home. This is a gay bar."
