you have to go to school and through the dialogue with the principal etc, then to the livingroom in the afternoon.
I do that, going to school, talk to the principal -the lines of dialogue are varied, but repeat at some point- in the morning and in the afternoon.
Then I explore the house in the afternoon, but the farest I get is into an endless loop of "Wait for late month", I seem to advance because sis comes to my room at night and talks to me while touching, but then rinse and repeat -"Wait for late month to come", "Go Inside the House", "Explore the House".
What am I doing wrong? I am not advancing from that first scene, even if I keep talking to the principal and so on.
