After the vice principal came on stage to speak, he invited Li Zaijing to come on stage to express his opinions.Li Zaijing understood that this was because he wrote a letter of complaint and exposed the school's problems.He came to the stage and said that violence is not a solution to the problem, and he will stand up to protect bullied students.At this time, Yin Zaimin appeared and kicked Pi Hanyu down with a sudden kick, questioning him whether it would hurt to be beaten, emphasizing that Hanyu is just an ordinary person and should not be arrogant.

Pi Hanyu's companions were frustrated by the failure to defeat Yoon Jaemin.Kim Soon-cheol went to the hospital to visit his grandfather. His grandfather was addicted to problem solving and believed that if he didn't study, he would lose the meaning of life.The hospital staff notified Kim Soon-cheol that the expenses were owed, and he requested grace and was understood.Kim Soon-cheol wanted to buy water but found that the money was not enough, Yoon Jae-min generously helped.During the conversation between the two, Kim Soon-chul learned about the reason why Yoon Jae-min was angry and asked about his mother's condition.Yoon Jaemin said that his mother was recovering and then talked about studying, while Kim Soon-cheol seemed absent-minded.Dazhe suddenly called and warned Kim Soon-cheol that someone was looking for him, but it was too late and those people had arrived.Yoon Jaemin asked about their intentions, but Kim Soon-chul stopped him from revealing his identity and urged him to leave.

When Yoon Jaemin visited Kim Soon-cheol grandfather, his grandfather hoped that he could persuade Kim Soon-cheol to pay attention to his studies.On the way home, Yoon Zaimin witnessed Dazhe being beaten, helped him and knocked down the perpetrator.The next day, the news came out that Kim Soon-cheol killed someone and escaped. Yoon Jae-min firmly believed in Kim Soon-cheol's innocence, especially his eyes when he left were full of desire for knowledge.

Yin Zaimin decided to find out the truth, and Li Zhiyu and others expressed their support.Kim Soon-cheol and others gathered and decided that Kim Soon-cheol would be punished.Yin Zaimin and others pretended to be members of Donald White and mingled inside, but were accidentally discovered. They pretended to go to the rooftop, but actually sneaked into the second floor.Li Zhiyu and Li Jun arrived on the second floor and found Yin Zaimin missing. It turned out that he hid on the rooftop and luckily avoided Pi Hanyu's search.But the rooftop door was locked and Yin Zaimin was trapped.Kim Se-hyun and others were venting news and found that Officer Luo Tae-wan was about to take Kim Soon-cheol away, and the situation was critical.Yin Zaimin tried desperately to open the door, but to no avail.

Li Jun stopped the pursuers outside and bought time for Li Zhiyu.Lee Ji-woo went deep into the office to search for the murderous weapon to prove Kim Soon-chul's innocence.When he found the key item, Pi Hanyu suddenly appeared. Li Zhiyu hid in an emergency, but Pi Hanyu had already noticed it.
