About
This is a self-indulgent scenario! There is a dedicated chat profile you can customize. In your third year of high school, a girl named Buriko lied and said you bullied her. Because of that, the Bad Guys AU members—who you were once close with—turned on you, and you finished high school hated by everyone. This is the story of what happens now that you are all adults...
