I also agree that having actual flashback sequences during the spoken exposition would be beneficial. Even if he doesn't change the dialogue, he could have it to where it shows you on screen the events that the character is explaining rather than just sound effects and being zoomed in on the speaking character's face.
Also on Chika, Quoting one of my past comments:
"You only have the option to have sex with her AFTER she told you. And she literally said it when she was first introduced. Not to mention the fact you can refuse to have sex with her and either way, sex or no sex, MC offers to help her find a real job."
and another:
"No, towards the end of the most recent version, she confirms herself that it is true. She explains the circumstances that got her into such a situation, and the player character offers to help her get a normal job and says he'd rather not see her working like this.
He even helps her confront her dad, and I have a feeling your assistance will bare fruits(meaning she'll get a normal job) in the next update. If not, idrc as I personally am not looking at her as a potential love interest.
I'm assuming in later updates, if you help her, she does eventually stop being a prostitute, but given that's her main issue at this point, I'm not sure how KS will make her story still matter after that.(I mean the message will still matter, but what will her story and conflicts be after she stops?)"
So if that helps answer your questions and concerns about Chika and why some people believe that people shouldn't be shitting giant bricks/being upset about her story, there ya go.
KS did a great job in that aspect.
