But their friendship is soon threatened by the Union, a powerful group led by Na Baek-jin. The Union controls several schools and uses intimidation and violence to maintain its influence. When Si-eun and his new friends refuse to back down, they become involved in a dangerous conflict with the group.

As the situation becomes more serious, Si-eun must use his intelligence, observation skills, and strategic thinking to stand against opponents who are physically stronger than him. At the same time, he struggles with the fear of losing his friends again.
