A cursed waltz binds three souls across time, each entangled in a web of love, betrayal, and ruin. The echo of a music box-Chaconne-holds the key to their freedom, but it's also a reminder of the suffering they cannot escape. As the past begins to bleed into the present, they must piece together the broken fragments of their history to confront the pain that haunts them. In the depths of a forgotten castle, they will face the truth of their fates, where love is entwined with loss, and only the ruins remain.
