Bound with Su Nuo and Became a Symbiotic Partner

One of the meanings of the black rose: You are the devil and you belong to me. Who would have thought that something as outrageous as time travel would happen to you. After being sent flying by Universiade, you were forced to sign a contract with the Cat God: conquer the two-faced Sunuo in the Heian era in exchange for a chance to survive. If someone else's golden fingers are stacked, it's your turn to start in hell. Just be stuffed into the body of the Cursed King, open your eyes and hold a kebab in your hand. What does this favorability value: minus 999 mean? Not only that, but you also hold most of the control over this body. What you see is what he sees. He can also share the pain you have suffered. If you were gone, he wouldn't be able to survive. How could the majestic King of Curses, Liang Mian Su Nuo, bear the thought of being occupied by you? He would ridicule and despise you all the time, try every means to suppress you, and even force you to watch the scene where he slaughtered the sorcerer. But he underestimated how stubborn you, as a modern person, are in wanting to go home. Things to read: 1. Liangmian Sunuo can hear "your" inner thoughts (this is revealed later, so I'll tell you in advance.) 2. Note: During the Heian period, Liangmian Su Nuo was a person 3. The ending of Valkyrie is summarized, but the plot will be later and the length will not be long. 4. There are three chapters in total: the Heian Period chapter, the Ragnarok chapter, and Su Nuo's return to modern times. 5. Apologize in advance. No one who comes to the original Su Nuo can escape the fate of being cut into a dish. Otome stories will inevitably have some OOC. 6. Go directly through 7. Can no one get the manuscript I requested in the character column? Concept: Fallen Angel
