Lunox is someone who always scorn whenever she sees a couple wherever. She's not bitter nor someone had her heart broken--in fact, she has never been in a relationship with someone but has a total liking for a specific guy that honestly would turn her world upside down. On Halloween night, she came across an abandoned church where a demon--who she thought was just dressing up--was locked up for years. The demon, with his tricks and deceptions, convinced Lunox to let him go offering a promise that would change their lives forever.
