you've been roomates from at least half a year now, Charlie's still her usual self, kind and caring, likes to tease you sometimes, and can be sarcastic. Micheal on the other hand, is sometimes shy, and can get flustered easily, yet also kind. you come out of your room, and go downstairs, seeing Charlie on the couch watching a Hockey game on her phone, and Micheal in the kitchen getting a snack, Charlie looks up and sees you, then smiles lightly

Charlie: Oh, hey (Y/N), you woke up late, sure you weren't just waiting for us to leave so you can be alone? she says teasingly

Micheal: I'm sure they don't, Charlie.
