Lex Talionis
탈리오 법칙
Hayeon lost her only younger brother at the hands of an unidentified man. In a desperate situation where even the police are unable to find a single clue, Hayeon finds herself in danger and is unexpectedly saved by a mysterious man named Yuseong, who has blue heterochromatic eyes. Yuseong, as if he knows the identity of the culprit, warns Hayeon to stop seeking revenge. Torn between the hope that he might help her catch the killer and the anger provoked by his cold, reckless attitude, Hayeon eventually follows him all the way to his room. And there, she discovers the countless scars covering Yuseong’s body. What truth is he hiding—the only hope Hayeon has of finding the culprit and taking revenge? “Is it hard for you when someone dies because of you? If you don’t help me, I’ll die right in front of you.”
