Not sure what ‘yk’ means but let me know if this doesn’t answer the question.
The demo does include some of this, so if you aren’t sure if the game is for you, please do play the demo first! What you see in the demo is very reflective of the game.
The demo also displays all warnings for every character on their route trigger warning page.
For all routes except Brandon:
In terms of content with minors, throughout the entire game there are REFERENCES to the main character’s childhood, which contained some dubious consent / sexual abuse from her biological brother who is 1 year older than her. That began around the age of 14 for her.
In the same manner, one of Quinn’s route paths also includes some historical references of him and his much younger sibling also being sexually abused by their stepfather.
By ‘references’, I mean these topics are verbally discussed in a historical manner during present day conversations with limited detail.
There are no active present-day descriptive scenes or CGs related to any form of sexual abuse of any minors. Everything is historic events.
However, Brandon’s route is different.
Brandon’s route specifically is excluded from the base game because his route takes place during some of those events. There are some scenes regarding their abusive relationship described in text (no CGs).
Brandon’s route is completely 100% optional and not included in the base game for that exact reason. So if that kind of content isn’t for you, you can entirely skip it without missing anything important in the overarching narrative.
If you have any further questions, don’t hesitate to ask. I’m also available in Discord or email if you want to discuss it further in depth.
