Irmentrude, the heiress of a viscounty, has memories of a past life.

Specifically, she harbors tragic memories of being cheated on by her husband, divorcing him, and subsequently being murdered by his lover. Because of this, she is hesitant about romance and marriage.

One day, when she, as a lord candidate, went for a work observation at the Knights' Order, her assigned instructor turned out to be none other than her past life's husband. Gilbert Musgrave, the Vice-Commander of the Knights' Order, is inexplicably doting towards Irmentrude from their very first encounter. Escorting her is a matter of course; he also insists on individual tutoring, sharing meals, and even bestows gifts upon her! What's more, he follows her everywhere. Is he a stalker? Is he truly a stalker?

This is a story about her — determined to avoid her past-life husband and forge her own path in this life — and him — trapped by the past and unable to move forward.
