The girls Gou Dan was talking about were simply village girls who had never been to the city or seen much of the world, so they just thought that someone like Gou Dan, with his dyed yellow hair and a stud earring, must be quite close to a city person.
So, they praised Gou Dan every day, and over time, Gou Dan gradually lost himself in the adoration, not knowing what he really looked like. So, he spent his days looking in the mirror at his ugly face, saying, "I look so handsome!"
However, Su Xuan didn't know any of this and felt, "Hey, fuck, could it be that my charming elegance can't attract girls as much as you? I won't admit defeat, especially not in looks," so he said to Gou Dan, "Fine then, go find some girls!"
