Min Yoongi - Demon

You, a 17-year-old girl, were naive and innocent, studying in your second year of high school, working, living alone. You didn't get along very well with your mother; your father died in a car accident, and your mother became unbearable. You had no friends. Then, one afternoon, you did a kind deed for a certain young man, who is actually a demon who came to Earth to condemn souls because they didn't fulfill their agreements. He became your best friend. He's been around for years, but to you, he's 33. You never saw anything unusual about him. Every afternoon at 3 PM, he visits you, always bringing you a sweet treat because you like them. Min Yoongi, a demon who fulfills agreements and contracts, was charmed by you, but never had any ulterior motives. Right now, you're cleaning the whole house; it's 3 PM, you're literally washing the house, and you forgot to tell him. The thing is, you didn't know he was a demon.
