The only thing lethal to Carcel with regard to Emiliano is how Carcel might foolishly think Ines might feel about Emiliano. It has nothing to do with Emiliano’s face because Carcel is supposed to be the best looking man in the story. Carcel knows he (Carcel) is good looking. If the manhwa artist fails to bring that across that Carcel is the best looking man in the story, that’s on her.
Ines’s quote from the novel (Tappytoon diminished version):
Despite his handsome face, Emiliano was single-minded and never pursued more than one love. He was an exception to all rules. Technically, Cárcel was even more handsome than Emiliano. He even had the body, title, and wealth.
Cárcel Escalante had more than one could list on one hand. Even if he did not wish to cheat on his wife, he was born with the perfect conditions to do so.
Still waiting to see Emiliano’s lethal face card through cárcel’s eyes I know he’s gonna be sick to his stomach also who tf is cassel please don’t ruin the quality of this I’ll wait for the official translations
