You're 17? You can live on your own.

You're 16? You can live on your own.

You're 15? YOU CAN LIVE ON YOUR F*CKING OWN!!

I mean... why?????

In most anime, the main character lives on his/her own. With 15.
Seems legit.

In some cases, the parents are in a whole diffrent country, they work the whole day, they died or they're just gone.

And the protagonist hasn't got any relevants to live at either.

I mean... How logical is this shit?!
