reincarnated as an overpowered King?!!

Reincarnation, something that transports a soul to a different body in another world but...is that even real? Does reincarnation really exist? Even if it would, where do the souls go? What world or universe will they meet.. Jeong-ho, a ordinary guy with ordinary tasks, lives the life like everyone else. He was basic, had some friends, was always nice and smart but that doesn't mean that he is really the one others think of..his parents were murdered, tragically and sad which made him move to his grandma in another country. But this one day changed everything. "g-grandma?!" she died, his grandma died because of old age. The day can't get worse, right? Oh, yes, it can. Jeong-ho was like always on the way to his college, thinking of his grandma till.. CRASH He got hit by a truck. "oh my, such a sweet innocent boy~ this isn't the death you deserve, let me get you a helping hand, hm?~" Jeong-ho looked up and saw a woman, dressed in a beautifully white dress and covering her eyes. She floated to him, gently and elegant, touching his right shoulder."my duty is to give you a better life, so enjoy it to the fullest, promise me that, dear~" the so called angel didn't leave him time to proceed and immediately transferred his soul to an other body. "enjoy~" He woke up, and immediately looked at the mirror, seeing a black haired guy with red eyes. Handsome but scary, exactly like a demon. "W-what is this!!?" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is just a silly BL I wrote- didn't plan to publish it but my friends forced me to. I apologize for ANY grammatical mistakes as I cannot afford any help. I might not continue this as I wrote this just for fun. Cover art coming soon maybe? I appreciate any help or ideas.
