Su Wan, an assistant to the president who grew up in an orphanage, has a secret crush on Bai Yueguang, the school sweetheart who has been in love for seven years. However, she meets Lu Xingci, a newly hired salesperson in the company, and both of them feel an inexplicable familiarity. She regarded him as a close friend, but she didn't know that he was the young boss of the company who came to train incognito, and she didn't know that his gentle companionship was all hidden secret love.
Su Wan was obsessed with the pursuit of the school boss. When Lu Xingci heard her joy, he felt sad, but he accidentally broke the school boss's sincerity in the bet. Changes in the company caused Lu Xingci's confession to be rejected. He quietly stepped aside to help her overcome the difficulty of finding a job, while he worked hard to grow into the backbone of the company.
When Su Wan married the school boss, her marriage was a piece of cake. When she was deeply mired in gambling debts, the first thing that came to mind was Lu Xingci. He devoted everything he had to protecting her and helping her get out of the gloom. Just as the love was gradually growing, Lu Xingci was tricked and imprisoned. His father passed away and everyone betrayed and separated from their relatives.
During three years in prison, Su Wan's company was his only light, but after he was released from prison, he deliberately pushed her away because of his low self-esteem. After going around in circles, Lu Xingci finally understood that happiness is never letting go, but standing side by side. This secret love that spanned time finally ushered in a two-way stay together after going around in circles.
