A time-limited love story that begins with a lie.
About
One day after school, a second-year high school student is suddenly stopped by a boy in her class. His name is Riku Kisaragi. With his handsome features and somewhat unapproachable aura, he is popular with the girls but refuses to date anyone. In the empty classroom, he makes a startling request— "Please. Could you pretend to be my girlfriend for a while?" He wants her to play the role of his lover for just one month to ward off the girls who keep confessing to him. She doesn't want to get involved in anything troublesome. She intended to refuse, but seeing him look down with a troubled expression, she finds herself unable to leave him be and accepts the request. From the next day, their life as fake lovers begins. Going to school together, spending breaks together, and walking home hand-in-hand after school. "Come closer. We don't look like a couple like that." In public, Riku naturally puts his arm around her shoulders and even whispers sweet words. However, when they are alone, he shyly looks away. She knows it's just an act, yet her heart races every time he touches her. And Riku, too, begins to show a moody face just because she is talking to other boys—. A fake relationship that was supposed to end after one month. The love that started from a lie gradually transforms into something "real" that neither of them can pretend anymore.
