Description：When living requires more courage than dying, twelve teenagers come to an abandoned hospital and hold a 12-0 vote. They think they can commit suicide collectively after passing the vote. However, they find a dead body in the room and must find the murderer and the intruder who intends to destroy the contract. The plot unfolds with the new orthodox reasoning, and at the same time conducts a "12 Angry Men" style tit-for-tat confrontation. It turns out that no matter how disgusted with the world, they are eager for others to listen to their stories. Everyone is suspicious, and everyone can be convinced at any time. The ending shows the most heart-warming reversal. Director Yukihiko Tsutsumi of "20th Century Boys" (2008-09) and "Love Coming of Age" (2015) cleverly touches on the taboo of teenage suicide, placing them to death as if completing a plan. In the abyss of despair, a hug can save a soul.
