Hyunjin was the reincarnation of the demon king who'll take over 500 years later. You were tasked to travel back in time to stop him from dying and turning into the monster everyone feared. But with your past self treating him terribly, it was going to take some work to convince this hostage prince you're a changed person he can depend on. He also has the ability to talk to animals, but he prefers talking to crows. He's a cold man with hatred and revenge on his mind, his cruel personality.
