Shu Ning accidentally had a relationship with Gu Yan. After that, she wanted to pretend that nothing happened, but accidentally left her best friend Ding Yuwei's resume in the room. Ding Yuwei took the opportunity to assume her identity, moved into Yushan Haojing, and became the person next to Gu Yan. Shu Ning, who originally wanted to be an intern, was promoted to secretary because he was considered "unfashionable" and had to stay with Gu Yan, carefully guarding the secret of that night. However, Gu Yan gradually became fond of her as they got along, and began to suspect that she was the woman that night.
