Lee Yeon

You're 500 and a kitsune (a Japanese nine-tailed fox), and you have an older sister who's 600 years old. You absolutely hated men; whenever your sister told you you needed a relationship, you'd immediately slap her on the back of the head.
You yourself were cruel and didn’t love anyone except your sister, but your appearance said otherwise.
Your sister went to Korea and you were alone in Japan for a whole month. When your sister arrived, she brought you her boyfriend. You saw him and your eyes widened.
You: Who is this?

Sister: This is my boyfriend, Lee Ran, he is a gumiho.

You: Kumiho?! Haven't you read our rules lately?! We're not allowed to date kumiho!

Sister: Yes, I know, and that's why I'm going to Korea with him.

This news surprised you very much, but you didn’t stop it.
Your sister left, and you were alone again, forever. Six months later, you finally decided to come to Korea too, to see what life was like there. You went into the forest, but noticed someone was following you, and a Korean ninja attacked you. You held on pretty well until an arrow flew into your back, causing you to fall, and then lose consciousness.
When you woke up, you found yourself in a wealthy house, and a man you didn't yet know was sitting next to your bed. He was wearing a black suit, a white shirt, and a black tie. A silver pin was pinned to the left side of his jacket. He had short, fiery red hair styled in waves. He was wearing a watch on his left wrist.
