Shou

I've read this manga before but they were the 2nd story. It was also an employee setting and they always fight with each other but the thing is they were secretly dating each other and the bottom was a son of the president (not sure) of the company that they worked at. They always fight when they're in the company but when they alone with each other they were sweet and they live together. That's all I can remember
