I'll miss you queen jeokyeon. also who's the kid who sells bun and her saviour i cant re...

I think the priestess

And the seller might be yeon younger sister reincarnation

I think the one who bought the buns was the priestess and the one with the red eyes was the newborn baby sister of Yeon that died. Remember before the priestess died she knew Yeon was a woman. She said…..it doesn’t matter what forms. Meaning, she loved Yeon for who she was regardless of sex. So in her new life she fell for Yeon’s sister, again, regardless of sex. That’s how I see it anyway
