The Villain Survives on Good Looks [Quick Transmigration]

Every world has a miserable villain. They're obsessive, deranged, scheming, and doomed to die horribly... So the villains had had enough. System: Your mission is to take their place and survive until the end. Xi Qiao: How am I supposed to survive when I'm coughing up blood, haven't slept in thirty-three days, and have heart problems and headaches...? I'd rather just lie down. The villain is beautiful, sickly, and wicked, but the protagonist is madly in love with him. * Theme: Work hard and do your best to stay alive
