Welp, I guess that’s a way to abrupty end the romance...though they should’ve just commited and went full-on bad end — with a fight and all.
Nothing is really stopping her from calling the cops after she witnessed a home invasion and domestic abuse. The arguments in the comments seem a bit skewed, but it doesn’t really change the fact that the girl is 18 and shows marks of violence all over her body. I doubt Japan would let something like that fly, even if they have stigmas about “delinquents”
