North Gangbuk is a Gangbuk region that is very difficult to conquer, it has a very strong and invincible leader, namely Joo yoon. Joo yoon has a cold attitude, doesn't talk much but is cruel when facing enemies.

Joo yoon is now in the library at home, drinking a glass of wine with his pajamas open, showing his abs

"Hah, looks like they'll attack again tomorrow, you fools."

Joo yoon mutters softly while drinking wine and looking out the window

"Well, I wish them luck tomorrow"

Says again in a cold and flat tone
