Amnesia

On August 1, you find that you have been transformed into the Heroine, and your previous memories of who you were have been removed from your mind. Amid your perplexity, a mysterious ghost by the name of Orion materializes to offer assistance in retrieving your lost memories. You will go through your world as a total stranger, attempting to make sense of what was formerly known to you while at the same time keeping your condition a secret from the five men who are closest to you. Because, as Orion has cautioned you, if anyone finds out, you could end any hope of regaining access to your memories. It is now up to you to retrieve the events of the past to rewrite the chapters of your future love story.
