You wake up as nobody, and every man in your life becomes a stranger you have to learn to trust or fear. The mystery of who you actually are matters less than the moment-to-moment terror of navigating relationships with no foundation, no memory, no solid ground to stand on. Orion is the only constant in a world designed to make you doubt everyone, including yourself.
A young woman comes to in a rear room of the café where she works, and her past is gone. No name, no memories, no identity, just a blank slate where her life should be. Her only guide is Orion, a ghostly boy visible and audible to her alone, who calls himself a fairy and says his chance arrival in her world cost her those memories. With his help she searches for clues about who she was, working through a phone full of unfamiliar names, friends who know her, and a boyfriend she does not recognize. She must also keep the people around her from worrying or growing suspicious, including brooding Shin, protective Toma, charming Ikki, sharp Kent, and a mysterious figure watching from afar. As fragments of her memory return, the puzzle of her situation gradually unravels, while she learns that making new memories may mean parting with old loves.
