that'd be fantastic, there's a small blurb about him up here: he's a 22 year old introvert that works at target and plays in a band. he's on the quieter side but isn't necessarily that shy when it comes to interacting. he's thoughtful and really into music so he can get really pretentious about that but he's self-aware that he is so he starts or ends a lot of rants with "i know this is pretentious bullshit BUT.." he's in the party boy/rockstar mode where he's partying all the time and way too drunk or high during his time off of work and that likely can get annoying to people but a lot of the scene he's a part of is like that and he hates having fomo.
but that's who he is now, i was thinking someone that knew him way back in even high school when matty was a huge mess that really needed to be on medication but wasn't, so his ups were very up and his downs very down and he tended to do a lot of crazy shit based off of some bad emotions. and now he's leveled out and a very subdued version of himself. his best friend would have stuck with him through it all despite the fact that his parents were in denial about his issues and meds and thought they could all pray and matty would fix his behavior. if that make sense!
