Why is the Demon King Teaming Up with Me Anonymously?

The sunny, ambitious girl vs. the cold, straight-laced Demon King. Shen Li transmigrated into the body of Sherry, a girl in a Western fantasy world who faces a death sentence simply because she is the betrothed of the Demon King. Caught in a corner with nowhere to turn, Shen Li decides to save herself: run away, go to school, become a landowner, and revolutionize magic! Soon, a mysterious man appears by her side and remains with her throughout her journey. He is a man who kills without mercy, devoid of human empathy, yet he wears a face so exquisite and otherworldly that it doesn’t seem human. When he speaks to her, his tone is gentle and cautious. Shen Li tests the waters with a hesitant paw. It isn’t until much later that she discovers this man is actually the Demon King, her fiancé, whom she has never met. Shen Li: “?” Garcia had known Shen Li’s identity for a long time. She was his fiancée, but due to various circumstances, he chose to keep it a secret. The moment he realized his own feelings, he couldn’t help but probe her: “I heard you had a fiancé before. What did you think of him?” Shen Li: “Him? He was alright. The best part about him was that he died.”
