About This Game

Story

You play as an amnesiac, piecing together fragmented memories to uncover the dark secrets both within yourself and hidden on the island.

One day, you notice that two of your regularly scheduled pills are missing.

That night, your dreams overflow with bizarre visions—the man who usually visits you on schedule transforms into a killer intent on ending your life.

At the same time, your therapist at the hospital has been replaced by a new doctor: gentle, caring… and unnervingly similar in appearance to your “boyfriend.”
