Abuse, rape & slavery victim/survivor becomes indebted to two beastmen... the past was way too sad and now that he's finally being treated well, he feels like he has to be useful n sh*t. Not a happy ending for me, I can't even read past few pages. And mangakas that write up such vile back story is so messed up! Reflect on yourselves!!!
