There are several completed workplace CEO secretly in love novels that I can recommend. One is "重新遇見顧先生" which tells the story of a female protagonist named 沈鳶 who pursues her long-time crush 顧流越 after her divorce. Another recommendation is "總裁暗戀我七年" which is a sweet and light-hearted story about a CEO named 鄧云樓 secretly in love with 葉真 for seven years. Unfortunately, the given search results do not provide specific titles for workplace CEO secretly in love novels.
