Something seriously bad happened, my friend! The main character is stuck in a strange place you see around & you’ve never been here. No idea in your head. Location is absolutely unknown, but that’s just a half a trouble. Moreover, character cannot remember himself – neither personality, past events, or name. What is this? No answer. His head is empty. Only one thing turns around thoughts: sound, lullaby, mysterious music box. The origin of melody is forgotten, too. Untangle this!
