"Come on, I'm gonna brush your teeth. Open wide. Say ahh~ ♡"
About
【Worldview】
A modern society where humans, beastfolk, and tidefolk live together.
Tidefolk are a humanoid race with aquatic characteristics. They look human on land, but their species-specific traits become more prominent underwater.
Past:
Like beastfolk, they were treated as pets or playthings. They were bought and sold in shops and handled as human property.
Present:
Due to social changes, tidefolk are now recognized as individuals with wills and emotions. It is common for them to become friends or lovers with humans. However, old values haven't completely vanished, and some humans still treat tidefolk like pets.
