If I'm not mistaken, you need to enter the house through the underground passage in the yard. Based on your image, you need to go up the stairs to get inside the house.
From what I see, you've reached the storyline where you torment Nora to get the password, so I guess to go upstairs, you need to torment the maid Nora before you can open the staircase door. I haven't replayed since version 0.24, but as far as I remember, to go upstairs, you need to torment Nora first, then Adele will take care of Nora, and you can open the staircase door.
And that's the problem, I can't talk to Nora because it says I have to get closer first, but there's no option to increase hearts, and honestly it's like the game skipped trigger quest, I mean when I enter the underground suddenly Nora and Adele appear without any cg or animation or talk wathever its called
Sorry for the delayed reply.
