He Yifeng, a business genius who was marginalized by his family, unexpectedly discovered on the day of his father's remarriage that he had an extra "sister" - Lin Ruoxi, who looked pitiful but was actually scheming. What shocked him even more was that this green tea daughter turned out to be his childhood sweetheart who had been missing for ten years.
Ten years ago, Lin Ruoxi designed to frame He Yifeng, causing him to be exiled overseas by his family. Now she has returned to the He family as a "stepsister". On the surface, she is gentle and pleasant, but secretly she is planning to annex the He Group. He Yifeng saw through her disguise and decided to use her trick to act out a "affectionate brother" drama with her.
But what he didn't know was that Lin Ruoxi's ambitions went far beyond that - she held the He family's business secrets for ten years, and colluded with foreign capital to completely erode the He Group within three months. And He Yifeng is just a pawn in her revenge plan.
The two confront each other under the undercurrent of superficial warmth, with murderous intent hidden behind every hug, and a carefully designed trap behind every "brother" sentence. When the truth gradually emerged, He Yifeng found that he not only had to deal with this green tea daughter, but also faced a shocking conspiracy that had been hidden for ten years - and this conspiracy was actually related to his missing mother.
