Hello. First of all, thank you for taking the time to play my little project full of cringe and depression, and for taking the time to leave this comment!
You mentioned that the last two events of Chapter 1 are the ones giving you trouble. In that case, I assume you're referring to "Eagerness to Pay" and "Saved by the Bell."
These two events are part of a chain. To trigger the first one, you need to have more than 12 Affection Points with Danielle and have visited Arisa at her job in the manga store at least once.
For any future questions, remember that you can always check the guide available in the in-game menu.
