no problem! no need to apologize at all <3 the reason i didn’t upload a purely choice based walkthrough is because if you want to get all CGs, simply change your response to the first choice in the very first life, aka
When Van asks you which picture you like in the bookstore, choose:
1) riverside (riverside variation of the final cg)
2) flower field (flower field variation of the final cg)
3) mountains (mountain variation of the final cg)
all other cgs naturally unlock as you progress through the game regardless of choice!
