I Tried to Run Away After Eating the Male Lead

After starving for several months, I picked up and ate unknown food in a temple I had entered to beg at, and when I opened my eyes again... A man called the devil who will destroy the world was in front of me. *"If you ate it, you should be responsible for what happens?"* I ate the source of his power, so he spit out strange words about taking responsibility. I have to get away from this madman before he splits my stomach! *"Body contact is the most effective way to exchange power between humans. The most effective method is to sleep together..."* *"Ah, this is reasonable. It can't be helped. It's good. One by one, step by step, shall we try it? Starting with sleeping together."* I couldn't ask him why it would be one by one, step by step. I felt like I would be eaten up just by his black eyes. Are you... Are you actually a villain who destroys the world with your beauty? (Source: KakaoPage, translated)
