When did Gang Shou take off his shoes?

In that episode, Gang Shou didn't punish Ueda. Because although Ueda's task failed, it was only a small task. In fact, when Gang Shou saw Ueda's prevarication and admitted his mistake, he felt very sorry. Seeing no one else in the office, he wanted to play a trick on Ueda. I pretended to be angry, tied up Youtian and said that I would be severely punished. Young Tian closed his eyes in fear, but what was waiting for him was that his shoes were taken off, and his feet were cold and itchy. In the face of Machamp's No.1 Gang Shou, Ueda's struggle was futile. She knew she couldn't laugh in front of Naruto. She could only sip her mouth and cover her face, but it even aroused Gang Shou's desire to play tricks on her. As Gang Shou's fingers touch the soles of his feet faster and faster, Ueda's mouth starts to rise slowly. This "punishment" is doomed to be long, but Gang Shou is not the kind of person who likes to bully the younger generation. She has taken off her shoes, because she knows that after this "punishment", the only way to make Oda accept her apology is to feel the same way. He couldn't help thinking, how long can he hold on without losing his temper with his hands under his feet?
