원수는 예비군 동원훈련에서

They say you always meet your worst enemies at military reserve training. When Yong-Taek runs into Wu-Chang in the training center’s restroom, he tries to offer a sincere apology for their messy high school past. But Wu-Chang 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 Wu-Chang; he just realized that sometimes, the only way to show love is through a very firm, very hard lesson. (Source: Lezhin US)
