Thank you! I wanted to explore Harry and Ginny as a couple that's so comfortable with each other, they've long accepted one another's personal quirks. Snape's been the "third wheel" all along -- it's just he's now suddenly manifested in physical form. But I totally do see how it may seem strange for Ginny to be so accepting; I'd actually toyed with different outcomes for the story when writing this, and one scenario was to have Harry more or less permanently assigned to the couch ;p
I'm glad you liked this, and thanks for sharing your thoughts!
