Fluent in Eight Languages, I Faked Being a Useless Translator for Three Years

The protagonist is fluent in eight languages, including German, but after three years at Zhonghe International Trading Company the resume lists only a TEM-8 in English, because he does not want to show off. Su Wanqing, head of the German team, mocks him for it—until she flounders in a business negotiation and he steps in to save it. Fearing for her position as team leader, Su Wanqing targets him even more deliberately. He had no wish to fight her, but the attacks keep coming, so he fights back, earning promotions and raises and changing jobs along the way, until he becomes the person his parents hoped he would be.
