Spoilers to get the Pie Ending!
Damn, this was quite heart breaking... The grief that Trisha went through was so obvious meanwhile Dani had to hold it in together. I can't imagine the pain he had to go through... Not only that, but the actions Trisha did had no excuse. But then again, to grieve is truly an ugly and painful thing to do... I just have to say that the art is superb, I love the expressions that were shown and how visceral they all feel, and the fact that you can see the mental deterioration that Trisha is going through so clearly is quite disturbing.
It's a wonderful sad tale, at the very least in the Pie Ending, while MC couldn't get in their dream job Trisha was finally stable enough. I do hope we do see an epilogue about what happened to MC and Trisha and Dani since MC suffered a lot.
Also, to get the Pie Ending is here!!!
Basically, you just need to be agreeable to Trisha. You need to agree and do what she says so she becomes attached to you and genuinely cares for you, but it's twisted in her grief. The scores you see are the choices you made.
Here is a more detailed one:
> I think we can fix it.
> Yeah we can work on that now.
> Fine.
> If you say so.
And there you have it, the ending with Okay or No doesn't really matter when you have no choice there. Hope this helps and this was quite a lovely gut wrenching visual novel! Spooky that's for sure, god I was terrified of the expressions and sound effects.
