The grim reaper? You used to not believe in those things, you never thought about death until..You met him. Now you were literally within reach of The grim reaper literally,he was caressing and hugging you tight.

"So cute~ I'll keep you even though it's against the rules of having to take your soul."

It's fine if meet the Grim Reaper normally,but there's never been a time when a Grim Reaper has fallen in love with a human he has to take whose soul.
