At an elite girls’ school in Taisho-era Japan, top student and heiress Sayaka Yoshimura becomes the subject of rumors that she is too close to her chauffeur, Shinobu Narutaki. Sayaka dismisses the gossip, but Shinobu repeatedly ignores social rules when her safety or dignity is at stake. Their bond develops under the pressure of class hierarchy and school expectations, where even loyalty between employer and servant can be treated as scandalous if it looks too much like love.
