Episode 4 recap: The Tiger Gang and the Four-Person Squad were competing.

The Tiger Gang was defeated and felt very angry. They were still thinking about seeking revenge. On the other hand, Li Changhai and the others were celebrating their victory. They said it was all thanks to Chen Liao's efforts. Everyone was shocked when they mentioned that Chen Liao climbed up a high flagpole without hesitation. Li Liao openly admitted that he didn't climb willingly. It was clear that they pushed him out. However, Li Changhai insisted that it was Chen Liao's accomplishment. As they were talking, the three of them held Li Liao down, and Li Changhai said he wanted to engrave something on Li Liao. He picked up a brush and without any hesitation, wrote the characters "War Wolf" on Li Liao's back!

The next day, the Four-Person Squad showcased the War Wolf pattern on various parts of their bodies in different poses. While they enjoyed the admiration of their female classmates, the teacher suddenly appeared and summoned them to the office! The teacher pointed at the patterns on their bodies and said they were dogs. The four of them argued back, but the teacher didn't listen and ordered them to clean up themselves properly. It was not allowed at school. After scolding them, the teacher let them leave.

When the four of them returned to the classroom, Li Liao went straight to Spring's position and asked her out for a moonlit night. Because of his three brothers, he had to say that it was the four of them inviting her! Li Liao didn't give Spring a chance to refuse and left directly. That night, the four of them waited at the agreed location, looking at the dark clouds in the sky and feeling deeply moved. At that moment, the teacher was searching for the person who stole his tire, and instinctively, the four of them started running! The teacher mistook them for thieves, and a chase ensued. The four of them quickly hid in a cabinet in the office, and even when the teacher arrived, he didn't find them!
