In a planet where negative emotions fester, five fairies from the most powerful clans are dispatched to Earth to gather "attachment" in order to keep their world going. To hide their actual identities and achieve their goal, the fairies construct Bar F and spend their lives as average high school lads and a barkeep. The lads meet a variety of female customers at Bar F, many of whom are harboring horrible thoughts in their hearts, and they offer to help them overcome their difficulties. The only thing they seek in exchange is permission to steal the client's heart. As the guys look into the source of each client's pain, they come discover someone who intends to sow chaos and immorality. With their goal in jeopardy, the fairies of Bar F must unmask this individual's identity and put a stop to their plans, all while holding true to themselves.
