In a realm where dark feelings grow, five sprites from the most powerful lineages are dispatched to Earth to gather 'bond' needed to keep their realm alive amid the ever‑shifting currents of hope and despair. The sprites open Bar F and pose as ordinary high‑school lads plus a bartender while navigating the complex web of human emotions to conceal their true selves while completing their task. At Bar F, they meet numerous female patrons, each concealing hidden anguish inside, and the lads pledge to aid them in healing with patience and empathy. Their sole request is the patron"s consent to capture their heart.
While probing each client"s sorrow, they discover a person intent on spreading ruin and vice. With their mission hanging by a thread, the Bar F sprites must expose this person"s identity and halt their schemes, all while staying true to themselves.
