You create relationships with any of the four people in the game. In addition, you can ask everyone about almost everything.
I'm just testing what I can do in Quest, as this is my first game.
=Hint=
Ask interests about "love" to get a general hint on how far you are in the relationship with them.
What are you supposed to do? Just pick up flowers and always get the same answer whenever you talk o someone? I'm sorry. But it just seems a little bit too boring anyways.
