@Shewy92 True but think of the social consequences. It's not the norm to take a girl years younger not to mention a generation younger than you to be in a romantic situation.
There have been cases but its a dark and thorny road ahead. Of course MC here wants none of it and handles it like a real adult.
Bah, just bang her, don't follow logic in manga. ^^
Sometimes i find it really irritating to force real life rules in some works (like you can't drink before you are 18, etc...). But i will follow nonetheless since the art is good and girls are cute. ?
