A business merger at the age of 18 forcibly tied the fate of the two young CEOs. Ling Yao, with his childhood trauma and innate coldness, regards this cooperation as just a springboard to expand his territory, uses indifference and alienation to draw boundaries, and refuses the penetration of any personal emotions; Su Muyang, with gentleness and empathy, tries to build a bridge of trust in the cold business rules. The ignorance when they first met and signed the contract, the deliberate isolation of the office floor, and the misunderstanding during the cooperation crisis caused the two to frequently confront each other under the framework of interests. When the shadow of Ling Yao's past was exposed by his opponent and malicious frame-ups ensued, his bad words crushed Su Muyang's kindness, but inadvertently glimpsed his gentleness and responsibility that silently filled the role. From tit-for-tat to ice-breaking testing, from pure business partners to mutual soul compatibility, the two 18-year-olds healed and supported each other in the ups and downs of the mall, and finally broke the shackles of "profit first" and turned the business landscape they jointly created into an exclusive world that carries each other's tenderness and bond.
