It was indeed not a big deal for Han Corporation to ban Bai Shuangshuang, a mere small celebrity.
But Bai Shuangshuang was his company's celebrity, keeping aside his private relationship with Bai Shuangshuang, if Han Corporation were true to their word and really banned Bai Shuangshuang, then he as the boss would lose his face completely.
Moreover, if other celebrities got to know that he could not even protect a celebrity under his company, who would dare to sign with his company?
Even the celebrities currently under his company would be worried sick.
