Reincarnation Life Simulator System: The Yandere Angel's Kept Man

"Darling, didn't I say not to meet women other than me? Why did you break our promise?!" "You won't blame me for sending you to heaven, right? Right?!" "After all, I'm only doing the end of our deal." "After I'm done, when the two of us are both in Heaven, I'll have your soul all to myself, with none of those vixens bothering our two-person world!" *** In a Modern World where there existed a supernatural side hidden from the public eye, the Biblical Pantheon and other divine pantheons existed. Lucian Halloway could attest that Heaven existed, as he was killed by Seraphine, his yandere girlfriend, and his soul was sent there. After rejecting the confession of one of his admirers, Lucian was caught by Seraphine and painlessly killed by her. His soul was caught by her, and taking advantage of her status as a Seraphim, Seraphine brought him to the Heaven Realm. Waking up, Lucian found himself in his girlfriend's mansion in the Heaven Realm. Upon waking up, he discovered that he had awakened the Reincarnation Life Simulator System! -Ding! [My Lord, the Reincarnation Life Simulator System is at your service!] -Ding! [Do you want to start a Reincarnation Life Simulation?] -Ding! [The Reincarnation Life Simulator System allows you to reincarnate in another world randomly and experience a life simulation there.] [I'm sure you've read other novels with protagonists who have a life simulator system.] [The difference between their life simulator and this system is that it emphasizes the aspect of Reincarnation.] [After you die in a reincarnation life simulation, you'll receive all the power and memories you have in that life.] [However, each time you die, while you'll still reincarnate in the same world until you complete it, you won't reincarnate in the same life and identity.] [Moreover, while you will receive all your power, you won't receive everything you've earned in the simulation.] [For example, before a reincarnation life simulation starts, you'll be able to choose three simulation talents from six simulation talent options.] [Every time a life simulation ends, your life simulation will be graded.] [According to your simulation score, you'll be able to choose simulation rewards like items you've earned in the simulation to be brought back to the real world.] [Not only that, but you will also be able to choose simulation talents. When simulation talents are chosen as rewards, not only will they be usable in the real world, but the subsequent reincarnation life simulations will inherit and equip them by default.] With the Reincarnation Life Simulator System, Lucian found himself experiencing different lives. However, he found one thing unusual: "Why are all the love interests I've had in each Reincarnation Life Simulations all named Seraphine? They even look the same as her and have the same personality as the real her." "She can even see and experience the Reincarnation Life Simulation with me!" *** {The synopsis is weak; please read at least ten chapters.} What to expect: 1. A kind but decisive protagonist. He won't always resort to violence, unless they truly court death. However, he isn't naive and also wouldn't sacrifice his girlfriend just for "the sake of the greater good". 2. A Main Character who loves his yandere girlfriend for who she is and accepts her flaws. This novel isn't a clickbait of claiming to have "Yandere" yet hating the yandere and wanting to escape from it. No, this is a based novel where the Yandere wins!
