Jiang Che once poured all his effort and energy into helping his childhood sweetheart start a business, only to be calculated against by the two of them alongside a vain man, suffering massive losses. Returning to a key node in the past, he soberly stops his losses, no longer blindly giving. Facing the three of them repeatedly acting arbitrarily and making trouble everywhere, Jiang firmly guards his bottom line, relying on rules and commercial means to protect himself. Later, he gets to know the insightful and steady Lei Jing, joining hands to develop steadily, while the three of them, due to their own shortsightedness and greed, ultimately reap what they sow and accept their corresponding price.
