Wow this comment section. Hot damn.
Seriously she asked a legitimate question here, Sayu can't stay forever and the longer she does, the worse its gonna be for our guy here. You're not going to have an easy time when the parents, police, court come knocking and asking you why you kept a girl...
Wow for a series that has such a fresh and unique premise, they really chose to go with outright overused cliches for its grand finale. Why?. This could have been a really good series but this is just disappointing.
