By the Deep Sea

Lin You, a descendant of a declining aristocracy, saw his mother's sapphire necklace at an auction house and vowed to redeem it. However, he fell into despair because the price exceeded his budget. At this time, Gu Huai, a business upstart, took the shot. Gu Huai once had a green love affair with Lin You, but they separated due to family opposition and misunderstanding. In order to get the necklace, Lin You became Gu Huai's personal assistant and suffered a lot of difficulties. However, during a business negotiation, she used her connections to promote cooperation and the relationship between the two eased. The necklace disappeared after three months, and Lin You received a mysterious package and an unfinished letter when she was desperate. Later, Lin You learned that Gu Huai's family business was involved in a business conspiracy. She and her friend Su Ran investigated and found that the mysterious organization was related to their family's decline. They fell into a trap during the operation, and Gu Huai rescued them in time. Just before the victory, the mysterious organization released a video showing that Gu Huai's father had participated in framing Lin You's family. The relationship between the two was once again at a deadlock, and the future was unclear.
