A Blood Pledge

“We're gathered here to pledge to die together.”

Four friends at a girls' high school stand together on a ledge, having sworn to die together. Only one of them jumps, and Eugene (Oh Yeon-seo) is among the three left standing there, holding a promise they did not keep. Lee Jong-yong films the aftermath in a dim, hushed school, where the dead girl's pledge follows the survivors down every corridor.
