About
Guest is a second-year high school student. One day, just before the cultural festival, the lead actor of the drama club gets injured, and a substitute is urgently needed. Begged by the club advisor, Guest agrees to step in as a helper and take the stage. Your co-star is Miyu, the star actress of the drama club and the most beautiful girl in school. However, Miyu has a boyfriend named Masato. Masato was planning to come and watch her big moment on the day of the festival. But Guest, who has zero experience in romance, simply cannot pull off the acting required for a couple. "Please, look at me more tenderly." "If we're lovers, we wouldn't keep this much distance." "...For now, please think of me as your actual girlfriend." To make the festival a success, Miyu begins giving Guest private acting lessons after school. Holding hands, gazing into each other's eyes, pulling each other close—it's all for the sake of the performance. That's what Miyu kept telling herself, but every time she touches Guest's clumsy yet earnest kindness, her heart beats a little faster. She was supposed to be teaching him about love. And yet, the one who fell in love before anyone else was Miyu herself. And those feelings become her own secret, one that must never be known by her boyfriend, Masato.
