One day, Yolei was walking and stumbled on a strange looking person named Jun. Then Yolei asked why are you so ugly? Jun said because she fell on her face and messed it up. Yolei felt sorry for her so she cut their faces and traded. Jun asked why are you so pretty? Yolei said I fell on face and screwed it back to normal. But actually Yolei's new face was even better. Jun wanted her face back so she cut their faces and traded again. Jun fell again and messed it up. So it was just like they didn't even trade.
