Seven years ago, Xu Yunshan had a momentary lapse in judgment and dated Yan Ting, the person he hated most. The day after they got together, he overheard Yan Ting telling a friend: "Who likes him? Just having some fun." After a fight that landed them in the principal’s office, their one-day relationship ended in disaster. Seven years later, Yan Ting skyrocketed to fame with one drama, becoming a celebrated film emperor, while Xu Yunshan was just a struggling makeup artist, drowning in debt after family misfortunes. When they meet again, tensions run high—yet they’re forced to work together on the same film set. Yan Ting: Don’t get any shady ideas about me. Xu Yunshan: Stay away from me outside of work. — That failed high school romance crushed Yan Ting’s pride. He never understood why—one baffling fight later, he was dumped. Seeing Xu Yunshan again, Yan Ting has one goal: make him bow his head in shame and kneel on the ground calling him "Daddy." If he fails, he’s a dog. Until one day, he accidentally catches Xu Yunshan alone, curled up in a corner wiping away tears. Red-rimmed eyes, a fragile gaze—one look, and Yan Ting’s resolve shatters. Fine. Yan Ting thinks. Being a dog isn’t so bad.
