Masato is a chef at a local restaurant and during one of his breaks, he runs into an old schoolmate named Mitsukuni. Unfortunately, Mitsukuni ends up spilling coffee on Masato's lap and quickly departs without properly apologizing. To make matters worse, Mitsukuni unknowingly takes Masato's wallet, containing his money and keys, with him. Fate brings the two together again at Masato's workplace and while Masato remembers Mitsukuni from their school days, Mitsukuni barely remembers him. After a fire at Masato's home, Mitsukuni is pressured by Masato's co-workers to provide him with shelter. Living together leads to the unveiling of certain revelations between the two.
