Lisalie works as a servant in the Orion Marquis’s mansion and falls in love with Hugo, the only son of the house. Despite the difference in social status, their feelings are strong, and their engagement is granted on the condition that she undergoes “bride training” at a prestigious boarding school for noble women.

Six months later, Lisalie returns eagerly to reunite with Hugo — but the Hugo she meets asks her, “Who are you…?” He has lost his memory. Thus begins a love fantasy where the noblewoman turned servant and the amnesiac marquis’s heir walk the path of a second chance at love.
