I’m not saying I don’t understand where you’re coming from And technically, you are not wrong But what you’re forgetting is this is a manga about humans with animal characteristics fictional fantasy They don’t have frontal lobes so he’s only about as mature as the author makes him. And inside the author makes him mature He just can’t communicate in their language
We can’t add realistic knowledge, or hypotheticals to a story, but have to go off of the facts based off of how the author wrote the characters
Morally it might feel wrong legally the character is 19 years, old and way past the age of consent
It’s also a manga about beast men
Main couple is cute and has issues fr but side couple? mermaid is 19 and teacher is like 24
