Question about Matty (by Complet's)

Hello everyone,

Does anyone know how to unlock all of Kaori Okano's (the Aunt) scenes?

I have 3 so far, the one you get before any choices are even made, the one where you she hears something at night and you go look for it and the one about the magazines she finds. I know at least I miss the bath scene and ending... (which pretty much means I never seem to get unto her "path" I guess?)

A walkthrough would be incredible, but just a hint of what you may or may not remember offhand could be enough, I'm at 85% completion and through looking up the cg's online, I confirmed all the scenes I missed are of her.

I have done countless playthroughs now, the last 5 or so were purely random, just because I seem to have tried everything that made sense '^^

For those not in the know, the game offers "choices" that really don't indicate which character you will interact with. I've tried quick saving and reloading with every choice that she wasn't in, but even that wasn't enough.

Any help would be very much appreciated, I'm at the end of my rope '^^
