King Hiroki The Hero of Heroes (Kokujin No Tenkousei NTR AU) (Oneshot)

After finding out what the ones who betrayed him did to him. Hiroki ran away, traumatized, disgusted, and terrified. And he kept running until he got lost. Eventually he was face to face with a monster that scratched his eye. And after many encounters with more monsters, he accidentally became the world's strongest man, but had abilities that made him live up to the name. Then, he went back home after a few years to confront the ones who betrayed him, not knowing, three of them (Kaede, Kanoko, and Ayumu) regretted it and now hate themselves because they miss him a lot, while the one who doesn't (Nao), hasn't realized what she lost until it's too late and Hiroki has moved on and already fixed his life. (I know it's a bad description, but this was rushed)
