in the first chapter, when haejoon finds blondie in the tent he says "where is that boy" and blondie's friends says "eungyung baek you're dead" and haejoon says "eunyung baek? but i was sure it was a boy who stole my wallet" so i thought blondie's name was a girl's name? then blondie confirmed herself(himself?) that she was a girl.
or was i confused? did it reveal that he was a boy in the next chapters? because i remember him having a girlfriend too.

im confused. in the first chapter they said blondie was a girl but later on they're referring to him as "he"
did i miss a part? were they trying to trick black hair by saying blondie was a girl or did everyone else forgot she was a girl?
