One of the progonists is a high-school student who left home when his father found out he was gay. Since then, he has been living alone in his uncle's apartment. His mother often comes to bring him food and check on him with his uncle, as the high-schooler doesn't want to see her. He meets the second protagonist in a park, playing with two children: he fights with with him every day, because he like to be hit?. But this man lives on the streets: he dries his clothes outside, collects free food to give to other homeless people, and sleeps in a sillo in the park. Except that one day, the sillos are withdrawn. But the first protagonist offers him a place to live. They get on well, even if they initially fall ill. One day, they go shopping together to use the natto coupons, but the homeless man is in fact being sought out by yakuza who seem to recognize him. As a result, the protagonist does everything to avoid being seen: wearing basic clothes, pretending to know how to play music and even hugging the high-schooler on a massage chair. Then, I don't know what's next
