Each choice you make influences not only your story but also shapes the emotions of those around you. When dark forces seek to steal the hearts you've collected, it's up to you to decide whose hearts to protect and whose to discard, all while grappling with your own sense of identity. Will you become a savior of love or a thief of trust?
