Lin Mao - an ordinary high school student, got drunk at the graduation party, woke up in the morning in a stranger's bed, and the other person was actually a man! It was so obvious that he had done such a thing to him, but the other person still felt it was normal. After escaping from the hotel, he thought it would be over like this. Unexpectedly, when he became an intern three years later, he would meet "him" as his boss. They were really enemies of each other. His boss's teasing reminded him of what happened three years ago. As time went by, he discovered that his best friend since childhood was actually the younger brother of that hateful boss, and he seemed to have different feelings for him. Just when he was in trouble, Lin Mao was surprised to find that the two brothers had an ulterior side. . . . .
