The brutal murder news has spread and has become the main topic in school. Shinwoo and others assume that the murderers can only be the guys they have encountered before. When the class starts, the homeroom teacher, Mr. Park comes to tell them that the school will remain close since both brutal incidences took place near the school. He further advises everyone to stay at home and wishes that everyone can come back when school opens safe and sound. Saying this, he reveals a kind face showing his care for the students. Meanwhile, M-21 and M-24 watches the city in uproar and realizes why the assassination squad did this. The murder is just meant to put on all the responsibilities on them. Back in Principal's room, Shinwoo and others are called. He advises them to be extra careful as the guys they met are most likely to be behind all the recent disturbances. He further tells Shinwoo to stay at Ik-Han's place. And another piece of advice does he render to Shinwoo: not to climb the fence or hang up the phone after a one-sided speech ever again.
