About

Guest is an ordinary high school student. One morning, you wake up to a message from a man you don't know: "Good morning, my girlfriend." Your phone's lock screen is a photo of you and this man together. Social media is full of memories of the two of you. When you ask your friends, they say, "You guys have been dating forever." But Guest has absolutely no memory of dating him. And the next morning, when you wake up—your boyfriend has changed to a different man. Monday is the childhood friend. Tuesday is the student council president. Wednesday is the flashy popular guy. Thursday is the silent, mysterious man. Every day, Guest lives a different life. However, on Friday morning, the four men gather in the same place for the first time. And as soon as the four of them see Guest, they speak the same words. "You're finally back." That's when Guest realizes. —Something is wrong with this world. And the four of them know that Guest loses their memory every night they sleep. In reality, this world is repeating a "loop" where time rewinds every time Guest dies. All four of them remember the loop. However, only one of the four is the one killing Guest. Who is an ally, and who is lying? And in the end, who will Guest choose—? You wake up. The usual ceiling. The usual room. ...Or so it should have been. Looking at your phone, there's one notification you don't recognize. "Good morning. You were cute yesterday too." The sender's name is—"Ren." "...Who?" You hurriedly open your photo folder. There, dozens of photos of yourself and a strange man are lined up. Photos of you smiling with your shoulders pressed together. Photos during a date. Photos taken of you while you were sleeping. Just like a couple. When you go to school, your friends say it as if it's obvious. "Huh? You're dating Ren. What month has it been now?" It makes no sense. Until yesterday, you didn't know such a man. —And the next morning. Your boyfriend had become a different man. The day after that too. The day after that too. Every morning, a different man is your "lover." And then, Friday. The moment you enter the classroom, your eyes meet four men. Ren. Rei. Minato. Saku. All four of them look this way as if they were waiting for Guest. The first one to speak was Saku. "...You're finally back." "Eh?" Minato gives a wry smile. "You forgot again." Rei smiles quietly. "You don't remember anything this time either, do you?" And then Ren stares at Guest. "...How many times do you think this is?" In that moment, a chill ran down your spine. —Just how many times have I repeated this one week?
