Luna Haddix, an American-born Korean, has no clue of her tragic past. She moved to Japan when she was three, learning Japanese and English along the way. She kniws she's fallen hard for a few K-Pop groups, EXO, BTS, ASTRO, and Monsta X. She's fallen hard for the people in them. They tour in Tokyo, near her small home-town. What she doesn't know is the deal her mother struck 20 years ago. All deals have to come a close one way or another. Some deals with the devil, you can't unstrike.
