I'm glad that the ending is a counterattack on the sound of the moon!

Kwang-jin, a born villain who has committed murder since childhood, proposed a survival game to Do-gi over Min-ho's stolen body. With the help of Do-gi, who had been turned into a "fighting dog" by Kwang-jin, and Go-eun (Pyo Ye-jin), Kwang-jin found him and launched a counterattack. Kwang-jin, caught in Do-gi's clutches, ended up buried alive.
