Yesterday I learned people in the anime community don't know who T.M. Revolution is. He's literally one of those artists where if I saw him on the opening credits of a show I'd get excited. 😭 This is proof we're all getting old.
This really depends though, if it's smth like, "there were burnt cigarettes littered on his desk" it's pretty much canon that guy smokes. If it's smth like "she wasn't good around men," that does not mean she's some man hater or gay
“implied = automatically canon” is the kind of mindset you grow when your only interaction with literature is through hoyoverse game lore and strange amounts of ship discourse
