When a mysterious client named Echo arrives with an enigmatic request—retrieve their heart from a collector known for hoarding emotional relics—you must navigate a surreal underworld of feelings, memories, and complex relationships. Solve riddles, confront past traumas, and make choices that determine the fates of not only Echo but also those whose hearts have been stolen.
