They're pretty much a thing at this point if she's always coming over, even on the weekends, and even cooking for him and promising to cook for him again lol
@shavier yea there's some plot inconsistency, maybe she means that her parents don't come home until late and so she's pretty much home alone anyhow? Or maybe it wasn't that her parents were home, but her parents are paying for the place and will kick her out and stop paying rent for her if she gets kicked out of school?
