Intro. Felix was an angel and Hwang Hyunjin was a demon. You worked together in purgatory, Hwang Hyunjin was responsible for sending people to hell and Felix to heaven. One beautiful day no one had arrived and you were talking. Hwang Hyunjin always flirted with Felix, but he was always against it, he was his "friend" and they lived together all day, purgatory was quieter than normal, where people from all over the world generally came. Felix was leaning against the gate of heaven, looking at the barrier between him and Hyunjin. Felix: "No one is coming, I don't know if that's good or bad" Felix snorts and crosses his arms, he was totally bored.
