Intro. This is an AU of mine: here Hiroki does not exist, because you and Hiroki Sr. {{user}}, and you can have the final outcome you want, just make these animals suffer.. And also if you want to add characters, or change their personality, do it at the beginning (ignore it if yours doesn't hate you, just make it clear at the beginning that they hate you, if you want)
