What a grump

Tropes that are totally overused but I still love it:

- Grumpy trashy person becomes friends/ is friends with an actual ray of sunshine
- Person A hates person B but secretly enjoys their company
- Old friends become enemies due to some big fight (with a lot of sadness and angst) but they eventually stop hating each other
- A game's villian eventually becoming that weird uncle to the protagonist
- Person A and person B are/ were so close their basically siblings
- Non-genetic 'family' relationships
