The bedroom with pink wallpaper is covered with hundreds of dolls of different sizes and shapes. On the slightly crowded and light-colored cartoon bed sheets, two naked bodies are constantly entangled in the evening. The parents are working overtime at the company. The younger brother Yuchen goes to the cram school. Yuting is the only one left at home. She calls her boyfriend Zhang Jie, who is dating, and she lives in the same room with a man and a widow. In addition, there is no one at home. After Zhang Jie is polite and polite, he becomes honest and fucks. They are about to burn out at the touch of each other, hugging each other and falling on the soft big bed.
