The Snake who loved a sparrow

Komazu is a sparrow, and as a sparrow, there’s one thing he knows about snakes: they eat small birds. When he encounters Shirato, the white snake, of course he expects the worst ― but instead of trying to eat him, Shirato saves him from a boar stampede and flees, teary-eyed, when Komazu lashes out in fear. When the sparrow realizes he's perhaps misjudged snakes and decides to learn more about Shirato, the two grow closer, first as friends and then as something more.

They are predator and natural prey, coming from different species and social castes; can love overcome the laws of nature, despite the differences in their way?
