After some time attempting a long-distance relationship, Shouji is crestfallen when he finds out his crush isn't gay. Having struggled with his sexuality for years, he tries to distract himself from the rejection, in part by helping out at the neighboring sweets shop — but when a young homeless man called Hama shows up at the store, Shouji finds himself curious to learn more about him.

Attempting to make their way in a society that labels each of them as 'outcasts' and 'dirty,' the two men grow closer. Together, they begin to find they have more in common than either of them could have anticipated.
