if you have done all the peek events and had the second date with cece, I suggest going there after a day or two and trying again. Like I stated in the walkthrough it isn't going to be exact every run of the game is different and what you are viewing is my fastest run. So you should use the walkthrough more like an event guide telling you where the next events are triggered and the best options for raising affection, not as a exact guide where if it doesn't happen on the day I wrote its a problem.
