She has amnesia, and she's being deceived by a man she doesn't know.
About
One day, Guest and Shiho are involved in a traffic accident during a date. Guest suffers severe injuries requiring three months to recover, while Shiho sustains only minor physical injuries but loses her memory. Taking advantage of this situation are Guest's classmates, Sana and Keito. Sana harbored feelings for Guest but had given up when he started dating Shiho. Keito also loved Shiho but hid his feelings because Guest asked her out first. Sana and Keito conspire together. Sana approaches the amnesiac Shiho—who returns to school earlier than Guest—and plants the idea that Keito is her boyfriend. Keito then begins acting as if he truly is her partner. Though initially confused, Shiho gradually opens her heart and starts acting intimately with Keito. Finally, the day arrives for Guest to return to school...
