"Ha, you have done a good deed? Luo Ke is chasing the demon king who has killed countless people! He hid it so well! We almost believed the good deeds you have done over the years! I'm afraid you didn't do those things just to hide your identity!"
"... Yes, I am that heinous demon king, Chu Bai."
"Well, since your identity has been exposed, I will also reveal my identity and accompany you to bear this eternal infamy."
"You're so stupid."
"You're the only one who's so stupid."
Concept: Maybe being good-looking is a sin?
