Sorry for the late reply! To get good end 1, make sure you don't press Shiori about the blouse when confronting her and you get evidence of all the items.
I'm dumb as rocks and also can't figure out good end 1 even with these instructions
Help please my brains mush
Did you get evidence of all the items?
Yes, examined every nook and cranny
Tried not asking at all about the blouse and asking once about the blouse too just in case
I may just be missing something with the kast 3 options
do not do the option where you tell Shiori you met Sendai-san, and then ask if they're friends
