it has been difficult as on top of not being able to remember TITLE or AUTHOR, I can't remember the plot of the story either just a scene

MC arrives at the digs (student lodging house) of her best friend (could be S\O) if I remember right he'd injured his leg.

The scene

for some reason she is in or near the kitchen (stereotypical male student house) bags of rubbish piled up waiting to be taken out, along with discarded pizza boxes some of which may have had 'science experiments' in them

anyway one of the occupants is drunk and won't rake 'NO' for an answer, and goes to grab her

he ends up amongst the pile of bags of rubbish

I think this is the final straw and he is evicted

this is all I can remember that is clear

Vague bits, car parked outside paint scratched maliciously, think that she had some kind of wind fall as car was new and of and expensive range.
