Maybe the first queen and the current queen are sworn sisters and the current queen fell for her, but the first queen aren't at the same page and marries the king. She get pregnant to the princess and totally forgotten her sister which made the current queen mad at the princess out of jealousy of her, taking the first queen's attention. Lol I'm sorry cuz I'm making my own plot.
He's not just a mere animal but omg this words means different things and that makes my heart flutter (๑•ㅂ•)و✧
