On the fifth anniversary of Rui Tachibana's pop star debut, his bandmate, Hibiki Shinjo, gains popularity among girls for his quiet and reserved nature. However, Hibiki takes pleasure in teasing Rui frequently, which their manager finds endearing and childlike. To prepare for an early photoshoot, Hibiki stays over at Rui's place since he struggles to wake up in the mornings. While Rui is in the bath, Hibiki ignores their warning and searches for their names online, stumbling upon a password-protected website that raises suspicions. To their surprise, fan-made manga on the website depicts them engaging in raunchy activities. Rui's imagination runs wild, and Hibiki suggests something daring.
