It's painful to love each other but not be able to stay together.
It's a pity that we know each other but can't fall in love.
After graduating from university, Su Yun arranged to work at the Institute of Ancient Writings, and soon Wang Yuanshi joined the institute. Su Yun likes to be quiet and study his own subjects; Wang Yuanshi still cannot do without people and sophistication, drinking and eating every day. One day, the arrival of Director Wu's daughter, Wu Haonan, made the small research institute restless...
When they met for the first time, Su Yun had an inexplicable feeling for Haonan, but it was difficult to express it. During the working days, the two gradually became familiar with each other and slowly entered each other's world. In fact, Wang Yuanshi has also been chasing Haonan, but she didn't agree. The three people fell into a love crisis. Just when the relationship between the three was unclear, Su Yun discovered that Director Wu was his biological father, and Haonan became his half-sister. Wang Yuanshi also heard some news about Su Yun and Haonan, and interfered with it. Su Yun kept looking for clues, but found that he, Haonan, and Wang Yuanshi were just chess players who had been arranged by their fathers. Su Yun and Haonan want to break through, but the future is dark! Turns out there's more to explore…
