You don't actually need one yet, just explore everything and pay some attention to the dialogue. Here is some things people tend to miss/not understand:
- On day one: You have to go to every place and talk to pretty much everybody, most people miss the Inn at the Medieval since the entrance is not below the sign but you need to talk to the pervy guy with white hair, he is your boss(always forget his name).
- There is also a day in the restaurant with zelda and the blonde girl(the one with the toys), that you have to decide whether or not to enter the bathroom before being able to progress.
- On the day of the party: there is a dialogue with the lifeguard about the guy with the flower(damn my memory's going), I'm assuming it's going to affect his relationship with her on future updates. Talking about the lifeguard, you have to visit the pool in the gym and talk to her to begin her stuff, on the first day if I remember correctly.
- The pool area is the same as the massage/sauna area, but I think you only get a massage on second day, that's why some people miss the lifeguard dialogue
(quest as well, I think).
