A sleepless maid’s night

I fell for a moment in the noble family, Youngae, and was like a maid in an acquaintance's house.
Eva Macys, who was living her hard life,
She accidentally meets her former fiancee, her Prince Edward.

It was only after her departure that he, who was strong and cold-hearted but kind to her,
Eva comes to her realization that he is her own first love, but
She gives up her current feelings, saying that this is the end of her relationship with him.
