A story of unrequited love between Takashi and his highschool friend Hayate, who rejected his feelings but then promised to go on a date with him for his birthday every year until Takashi finds somebody he likes more than him. Hayate has diligently kept his promised for ten years, but Takashi, still painfully in love with him after all these years, has reached the point where he cannot go on with these yearly meetings.
