I can't like anyone in this story.
MC is shallow and easily blinded by looks (true core of Korean, I suppose?)
ML is meh
Villain is stupid and delusional, being hostile for no reason.
Second prince is nonrecycleable trash and piece of shit who cannot do anything but use clueless people for his own gain without any consideration, would hate it if he becomes the king.
The sister is too naive about living as a commoner.
I feel stuffy reading this, like, gurl, you died once, grow up and start looking beyond the face, GEEZ!
Theo and Iona cuddling together... IS. JUST. TOO. CUTE. FOR. MY. HEART.
