Gender-bending + Western fantasy + nearly invincible protagonist + System After flirting with the kingdom's saintess, Catalina used the System to fake her death. She thought everything had gone perfectly, never imagining she'd end up as her arranged marriage partner! "You look just like him. You have to be him, don't you, Catalina!" The next moment, their red lips met. "No, I'm not, mm..." "You are him. I don't remember for sure, but that doesn't mean it couldn't be him."
