The pseudo-delinquent Song Ye was suspended from class because of a fight. He came to the GAY bar to vent his anger. Unexpectedly, he met his class teacher Mai Yusang. Drunk Song Ye mistook Mai Yusang for Liu Mo and had a relationship with him. (So cruel! He actually forced Teacher Mai, who only does top, to do bottom)
In a sense, Mai Yusang gave his first forehead...
