Yu Jung-ak's recent routine had changed quite a bit. Previously, he had focused on striking practice, but now he had minimized striking training and was practicing ground work. At first, Yu Jung-ak struggled to adapt to ground training, but at some point, he started to adjust well. And he was learning faster.

Yoon Hong-seok was overseeing Yu Jung-ak's training even though it was daytime. Yu Jung-ak was sparring in jiu-jitsu with Angela. Due to the significant weight difference, Yu Jung-ak was given a penalty: he wasn't allowed to use strength to break techniques. He had to counter technique with technique.
