a girl
No Arin's a boy, they just made him wear the dress and other things because they needed a replacement for Princess Ione because something happened to her. He just looks like a girl.
ah right i got the one in the desc and the story mixed up
He's a man but playing a girl hole until now at least
oh okay thank youu
Unless the parents don't know the gender of their own child however they kept calling Erin "Daughter" perhaps during transformation Erin transformed into a boy.
His parents always called him as He. You're just little confused
Arin is a Boy. Read the novel or the original in korean the author adress him as He/his just like Oppa & Noona in korean.Dragon was pretending to be a girl and looks like a gal just like Atisse
Wait is Arin a boy or a girl ;-;
