Hi, sorry if something is misspelled, I'm using translator to write this, sorry in advance! ;;;
Possibly the two endings you are missing, are the ones you get when you don't talk to Rebecca again, after her introduction event and go straight to Circe's house after that. Which paves the way for the two possible endings: having a single candy in Julie's game, or getting no candy at all.
Hope this is helpful for you, thanks so much for playing! <3
