Minh Mint's Links
Minnie is Minh's stoic caretaker that's always with him. She never blinks and her expression is about as emotionless as a rock, but she does her job damn well, so that doesn't really matter much to him. He's a bit grouchy around her, but she doesn't seem to mind and can handle him fine.
Minh is the guy she's looking after, so he's important. It's her duty to keep him safe and well. She will stare down at him every night while tucking him in bed.
