heyyy!! these are the things I did to get the third image:
1- fail every single one of the questions Kawa made
2-when they give you the option to explore your room, dont do anything except doing your makeup
3- from the moment we first encounter with Hikaru here are the options I picked that led me to the image (maybe other options also work, but these are the ones I used):
-Option 2
-Option 1
-Option 1
-Option 1
-Option 2
