Reborn as Bakugo brother(MHA)

An anime fan gets hit by a truck and meets a bad ROB wanting to throw him in a hypnosis hentai world as one the heroine. Sacrificing his wishes so he doesn’t get raped, he reincarnates in the world my hero academia as Katsuki bakugo’s brother. I’m new to writing so the chapters may be short, idk how to write long ones. Please give me any suggestion or comments, it would help me a lot.
