Honestly, with how shitty everyone in this game was, the harem ending was probably the best thing yet. Though I really wish there was a selfless ending where the MC let's his anger go after teaching them all a lesson and freeing them rather than letting them kill you and they all forget.
LOL. The blonde's motives (social pressure and only wanting alpha males around) might be the least-worst reason to bully MC, but she's still just as evil as the rest of them.
After completing the game, I kinda wish that we can replay the battle scenes after the ending and have em act like the ending happened instead of going back in time to when they first do it.
