Chen Chen has a younger brother. That younger brother seemed to steal all the attention from his parents. He was unwilling to accept that he could have inherited the family business, but in the end everything was taken away by his younger brother. Parents' expectations, girlfriend's admiration, brothers' flattery. Whenever his younger brother approaches him and wants to act coquettishly, he will put on a stern face and smile sarcastically, and then his younger brother will leave feeling disappointed. Until one day, he saw his younger brother sitting on his bed, holding his clothes in his hand. The obsessive smell in the room, the heavy breathing, and the constant sound of his name... Something seemed to be changing.
