Short version: She is a spy who enters a manor as a maid to carry out a mission and meets two happy enemies. One young master is casual and lazy, while the other young master is indifferent and quiet. The old love is unforgettable, her heart has long been with someone else. In this dark mission, she struggles between love and responsibility.
Comedy version: Oh my god, I just sneaked into this manor to work as a maid to carry out a mission. Why have I already met these two young masters? They are all enemies! Wouldn't it be miserable for them to deal with it in the future?
Affectionate version: I can't forget him, even though I love you very much now. But I can't forget the pain and happiness he gave me. I'm just here to perform a cold mission, not to find warm love. I want to leave.
