Su Su, the head of the R&D department, is being watched silently by his subordinate Lin Ye, who is three years younger than him and is known as "White Moonlight". Lin Ye seems cold and cold, but in fact he hides his "little wolf dog" nature. He delivers porridge and medicine to Su Su when she stays up late. After being drunk, he forcefully escorts her home and confesses to her, and the two establish their relationship.
After falling in love, Lin Ye secretly doted on Su Su in the company, and was clingy and protective in private. Faced with the gossip about "sister-brother love", he firmly protected her in front of the entire company. In the end, Lin Ye used his domineering and gentle protection to prove that age is never an obstacle, making Su Su understand that he is not only her "little wolf dog", but also the "moon in the palm" and candy in her heart that she can entrust to her for the rest of her life.
