Drills, Discipline, Desire

They say you always meet your worst enemies at military reserve training. When Yong-taek runs into Wuchang in the training center's restroom, he tries to offer a sincere apology for their messy high school past. But Wuchang hasn't changed a bit, throwing insults and mocking Yong-taek's family until something finally snaps. Yong-taek decides it's time for a different kind of "discipline." He never hated Wuchang; he just realized that sometimes, the only way to show love is through a very firm, very hard lesson.
