How do I open a event with breakfast in the kitchen?
There is a panel you can open with the double arrow button near the top left of the screen. Once that panel opens, if you click/tap on a character, you'll see what the next step with them is. Generally, events in this game will require a few things:
- A certain amount of love: check the number of "Points" indicated. You add points by talking to / petting the appropriate character.
- A certain location: This can also sometimes require a certain time of day, so make note of that.
- A certain prerequisite event: Sometimes an event has to happen first. IIRC, you'll still be told to go to a certain place at a certain time (like the island fire in the middle of the night) in order to kick off a relationship with the next character.
- A certain special item (rare): It's not very often, but sometimes you'll need to get certain item(s) in order to progress. The game should tell you what you need, but I can try to help you if you get stuck.
BTW, if you're having trouble finding the shattered star pieces at any point (or the hidden wallpapers, if you want them), you can consult
my list here to see how to get them.
So, to answer your specific question, it depends on the event, but I would say it's going just to require (1) enough love/points for the character involved; and (2) going to the kitchen at a certain time of day.
