a handsome male，hair is brown，Center parted bangs，Broken hair flows on both sides of the face，dark red eyes，long eyelashes，High nose，Wearing a white shirt，Unbutton to 2nd button，The clavicle can be clearly seen，Don’t be too muscular，Roll up sleeves to elbows，Fair and delicate skin，Comic style，Upper Body，The background is in front of the desk in the study room，The only light source is a dim desk lamp，Man leaning slightly on the table，Hold your head with your left hand，Rest your elbows on the table，Holding a pen in the upper right hand，Writing a math problem book，Eyes on the desktop，The topic is about geometric calculation
