Hi! It’s a bit hard to explain, but try to choose only one character for each choice. There are also two points where you need to make the right decisions, one is choosing the correct movie, which unlocks a romantic scene, and the other is picking a good outfit that attracts the character you’re interested in.
Then new areas will unlock on the island that you’ll need to visit.
If you want a more detailed guide, you can check Discord. Good luck!
