Luciel strived to survive in a world that was suddenly plunged into chaos by monsters. Unfortunately, the base he was staying at didn’t survive the monster tide. So, after surviving in such a world for 7 years, he died. Luciel thought he had died, but when he opened his eyes, he was met with peaceful modern scenery. After looking around, Luciel laughed with joy and said, “Ha ha ha. I can finally enjoy such peaceful scenery again! No more eating expired food! No more sleeping in the open space! And there is no need to fight daily! To whomever brought me here, thank you very much. I will enjoy this life to the fullest!” He also woke up in the body of a male model who had just signed to be the contract lover of their boss. "Hmm, $5 million and a house in the capital as a separation fee, and $100,000 as an allowance every month. The boss also has a handsome face. Ok, no problem!” Luciel did enjoy his peaceful life for a few weeks, but afterwards he found out that the world he was in was the apocalyptic novel he read in his past life. He didn’t want to live in the same way as his past life, so knowing that he was the lover of the protagonist who died in the first chapter because he ran away, he decided to stay and rely on the protagonist. Luciel just wanted to rely on the protagonist to have a better life in the upcoming zombie apocalypse. However, he was forced to deal with the people flocking around to rely on the protagonist, and he was even forced to fight again just to save him. “Hey! I just want to rely on you! Why do I need to deal with a lot of things?” “It’s not my fault that some things happened.” “What did you say?” “Don’t stare at me with such a cold look. Don’t worry; you can continue to relax and just rely on me. You don’t need to care about anything else, as long as you care about me!” “Huh? Are you still dreaming?” ------------ This is a story about how Luciel lives in another apocalyptic world and how his contract relationship with Treyton turned into a real relationship.
