People getting mad about Chika when her story isn't even finished yet. I'll admit, it isn't something I enjoy the thought of either, but like, her story isn't finished yet? Character development and shit exists you know?
That's like booting up a game and never playing it again because the main character was an asshole in the prologue. A good story has characters that grow, develop, and change as it progresses. Sure, that's who Chika is right now, but who knows who she'll become as the story progresses? Maybe it'll turn out she has the best character development and story in the game? Or, it turns out she has the worst... Who knows? Game's not complete yet so nobody knows.
But I do have a few predictions as to why she does what she does. I mean are we gonna ignore that scene with Chika at her house? "Just go make more!" and "If she never had you...She would still be..." It's quite easy to see it's her drunk, abusive father who blames her for her mother's death. Chika has daddy issues, comes from a poor family, and she has to make money somehow. I wouldn't blame someone for doing that if that was their situation in real life. Hell, the main character even says that she might be able to make a difference in the future.
Anyways, it's still a bit of a controversial choice but hey, I am curious to see how her story goes.
