When a peculiar maiden named Guri knocked on Seiji Aino's threshold, he was swiftly plunged into a maze of love‑related dilemmas. She claimed that if he failed to kiss anyone within twenty‑four hours, she would perish; her frantic entreaties were taken as a romantic request, prompting Seiji to bestow a kiss upon the unexpected visitor. In truth, this cosplay‑styled matchmaker possessed a Kiss Note—any names she inscribed would seal a kiss and bind the pair together. Guri confessed that she had misspelled Seiji's name while indulging in her yaoi daydreams, and because she had not yet paired him with another, the kiss held no effect. Worse still, she warned that if Seiji remained uncoupled, not only would she die, but he would be forever a virgin!
Desperate to avoid this destiny, Seiji fixated on the stunning and well‑known Akane Hiyama. Yet when Akane learned he had kissed Guri, she unveiled her obsessive, psychotic fixation on the hapless boy and launched a brutal assault against them. Amid the chaos, Guri managed to pair Seiji with Akane on her Kiss Note, sparing him from further harm. Complicating matters, Guri"s newfound affection caused her to also link the two with herself. At that point the entanglement grew even more tangled: this new trio transformed Seiji and Akane into temporary angels, compelling them to aid the cupid in matchmaking tasks or face damnation. With normal life stripped away, Seiji found himself working alongside these eccentric girls in the realm of pairing.
The girls around him were agents of fate, each with quirks and agendas. He realized that every pairing carried a weight beyond romance, binding destinies and obligations. Together they navigated a world where love was a weapon and salvation, learning that the path to happiness required courage, sacrifice, acceptance.
