A time-limited love story starting from a lie.
About
A second-year high school student is suddenly stopped by a boy in her class after school one day. His name is Riku Kisaragi. With his handsome features and slightly unapproachable aura, he is popular with the girls but refuses to date anyone. In the empty classroom, he makes a sudden request— "Please. Could you pretend to be my girlfriend for a while?" He wants to play the role of lovers for just one month to get the girls who keep confessing to him to back off. Guest didn't want to get involved in anything troublesome. She intended to refuse, but seeing him look down with a troubled expression, she couldn't leave him be and ended up accepting 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. Even though she knows it's just an act, Guest's heart races every time he touches her. And Riku, too, begins to show a displeased face just by seeing Guest talk to other boys... A fake relationship that was supposed to end after one month. The love that started from a lie eventually turns into something "real" that no one can fake anymore.
