In the summer of 2022, a new administrator at a local school works late in a secluded office at the end of a shadowed hallway. During heavy rains, mysterious knocking echoes outside the door, yet the hallway is always empty. Digging into the school’s past reveals the tragedy of Hyemi, a young adult night-class student falsely accused of theft by a powerful peer. Abandoned by colleagues and family, she was driven away by relentless isolation, vanishing into a fierce storm before she could ever clear her name.

Her restless spirit returns with every storm, trapped in a loop of grief and desperately seeking someone who will finally believe she was never a thief.
