Satoru had a washing machine at home.. that had walls inside. They were there so that the water wouldn't accidentally leak out. One day, when he came to Satoru's house, Suguru wanted to hang up his clothes. He climbed into the washing machine, but suddenly those very sides pinched him, not allowing him to get out. And he didn't know how to remove them. Suguru called Satoru to help him, but... Satoru was in love with Suguru.. So... maybe this was his chance?
