Su Tang out of spite custom-ordered a robot identical in appearance to her childhood sweetheart, while the male lead deliberately disguised himself as a robot to redeem himself, suppressing his emotions, obeying in everything, and even pretending to have system glitches when jealous. The female lead sees through the truth but doesn't expose it, taking the opportunity to tease and test him. Amidst their daily bickering full of laughs, they resolve past misunderstandings, face the love deeply hidden in their hearts, and ultimately make up and stay together.
