A high school student finds themselves drawn into an enigmatic club during their final week before graduation, one whose members have made a collective pact to end their lives within seven days. The protagonist, initially driven by their own suicidal ideation and social withdrawal, encounters the group's recruitment poster and joins out of a mixture of curiosity and despair. However, as the severity of the members' intentions becomes clear, the protagonist experiences a sudden reversal—a desperate wish to live—yet remains trapped by fear and complicity, unable to voice their change of heart to the five boys who are already committed to their fatal plan. What follows is an uncomfortable week of proximity to darkness as the protagonist silently witnesses the group's final days, caught between the desire to help and the paralyzing inability to act.
