A NALU STORY My Particular Boyfriend

Lucy is a young and outstanding doctor. One day she is assigned to take care of a particular patient who has mental dysfunction or this is what his parents say.
She doesn't know anything about him.
He behaves childlike with her and she sees him as a cute and innocent child but she doesn't know that...

This is my second nalu story, the characters are all Hiro Mashima's, I only own the story. I apologies if there are mistakes and for the rest I hope you'll like my story.
