Don’t know if you could help me maybe? I’ve got all the romance and friendships, the squad, the dreamer, the hikimori(?), the one where you focus on all of the passions, and I have all of the things filled with all the characters, self, friendship and passion encounters. I’m not sure what I’m supposed to do now?
