Dean is usually seen as a soft person, so I don't really want none of that usual fluffy texting stuff- I know I am innovative, thank you, thank you. Anyway, maybe something like... Him being really passionate when it comes to... i don't know, random bets between friends, and he's really fired up to win, internally, and you know about it just from looking at him, so you poke fun at him about it but he's in denial- Dean is impossible to not be fluffy, because this is fluffy, what the heck Hyuk?
so he’s really focused on winning this bet, being a competitive butt and you make fun of him?? yes!
