Bedtime

The emperor must be gradually destroyed from within.

Assassin So-Hwa enters the palace to use a beauty trick on the tyrant Yu Ge-On. However, Yu Ge-On suffers from obsessive-compulsive disorder and madness, which makes him absolutely unwilling to approach women.

"If you touch me, you will become dirty too."

One night, when the emperor's madness is at its peak, So-Hwa stands guard in Yu Ge-On's bedroom and tries to take him down, and Yu Ge-On, who has fallen for So-Hwa, begins to become increasingly obsessed with her.
