This marks the first crossover in the Blue String Universe. The main characters from Get Schooled, Study Group, and To Not Die collide in an epic showdown. This is the untold story of a brutal fight that wasn’t covered in their individual stories.
Living as the leader of a runaway family after being abandoned by his home, “Yim Dajun” faces the challenges of survival. When he finally brings him Yeonu, a chain of events is set in motion, leading to a violent incident involving a weapon in Incheon. As Yeonu attempts to assassinate a chaebol chairman, the plan is thwarted by “Yun Gamin,” the strongest boy who dreams of becoming the valedictorian. Meanwhile, “Na Hwajin” from the Educational Rights Department observes the unfolding chaos with keen interest.
