Izumi Sena, born into a family of entertainers, defies expectations by pursuing a career as a manga artist instead of following his relatives' footsteps. Unexpectedly, a reunion with Ryouma Ichijou, a famous actor who has harbored a long-standing affection for Izumi since their childhood commercial shoot, turns Izumi's world upside down. Complicating matters is Ryouma's mistaken belief that Izumi is actually a girl, a misconception that persists despite the passage of time. As Izumi grapples with this revelation, Ryouma's persistent feelings pose a new set of challenges that threaten to disrupt Izumi's life even further.
