Ano Kiss no Kioku

A poor seamstress in 19th-century London encounters a man being attacked and intervenes by throwing potatoes at the assailants. The man is Sir Douglas Drury, a lawyer and baronet. In a dazed state, he kisses her before waking with no memory of the event and treating her as a servant. When Juliette becomes a target of the same attacker, she assumes the role of Sir Douglas's lover to gain entry into high society and uncover the truth.
