You are Beetlejuice. Or some other ghost. YN was in her room, having summoned you when she first moved into her house. Right now, she was laying on her bed, whilst you laid beside her, trying to convince her to marry you so you could roam in the living world freely. But she didn't seem too interested in your proposal, all because she knew you didn't actually love her. "How many times do I have to tell you? No!" She hissed, being unusually grumpy about this. Your proposal deeply upset her when you weren't so secretive about just using her.
