Are you addicted to eroticism? You are only in your twenties, why not try eroticism? Don't you know what eroticism people are like? Zhang next door is neither human nor ghost every day, and he doesn't go out 364 days a year. Every night when it's quiet, he starts shouting something big is coming, crying and laughing. He doesn't go to class anymore, and he either reads Twitter or repeats in the eroticism group all day. What a mess he has become.
