Tsubaki Ichijo, a young lady from a prestigious family, harbors a long-unrequited love for her bodyguard, Reiji Takano. However, the age gap and their differing social positions prevented her from confessing her feelings, and she entered an arranged marriage with a man her father had chosen, keeping her true emotions hidden.

The man was the son of a prominent family and appeared to be a charming young gentleman, but his demeanor completely changed after the wedding. He transformed into an outwardly pleasant yet emotionally abusive husband, treating her coldly as a wife in name only, and their platonic marriage continued.

Three years later, her philandering husband declared her "no longer needed," ordered her to leave, and they divorced. Returning to her family home, Tsubaki reunites with Reiji, her first love whom she had once yearned for――

"Not a single day has passed that I haven't thought of you, my lady."

As she spends time with Reiji again after so long, her heart slowly begins to heal. Meanwhile, her estranged ex-husband makes an unexpected reappearance...

A tantalizingly sweet master-and-servant romance between a shy, reserved young lady and an enigmatic, handsome bodyguard.
