A girl disguises herself as a boy to chase her idol, then has to actually live that lie in an all-boys dorm while falling for him in real time. The show spends zero energy on whether her cover will hold, it's about the impossible math of loving someone while pretending to be someone else. Every moment she almost gets caught, every conversation where she has to swallow what she actually feels, every time Sano gets closer to the real her without knowing it exists, that's the actual tension. The comedy comes from her doing parkour around her own heart. Romance built on a secret this deliberate doesn't resolve when they kiss; it resolves when he knows her actual name.
Mizuki has an obsession: Izumi Sano, the high jump champion who saved her life years ago. When she learns he's attending an elite all-boys academy, she makes a radical choice. She cuts her hair, binds her chest, and enrolls under a fake identity to finally meet him. The problem arrives immediately. Sano has abandoned high jump entirely, leaving Mizuki scrambling to understand why. Between attending classes as "Mizuki Ashiya," sharing a dorm room with curious classmates, and navigating the minefield of communal bathrooms and sports festivals, her disguise feels paper-thin. Every close call risks exposure. Every moment with Sano feels charged with the possibility that he'll see through her act. What starts as a simple stalking mission becomes something messier. Living among these boys forces real friendships to form. Sano's distance from athletics hints at deeper pain. And Mizuki begins questioning whether the idol she worshipped matches the complicated person actually in front of her. Comedy and heartache collide as she tries to keep her cover intact while getting closer to understanding the real Sano.
