Fics like Shirogane's Harem at War

Au- Becoming aware of a cliched life of being a harem romcom protagonist was one thing, but believing that you're brocon stepsister, a school largely comprised of girls, and your busty childhood friend have it out for you was something Shirogane Miyuki never expected to actually happen. Some tropes were too ridiculous, but all of them totally plausible in this scenario, and Miyuki is going to take full advantage of all of it.
