If you have a character with a penchant for poking around the hallways after-hours, they've probably heard Adrien's Tchaikovsky echoing through some corridor in the distance or caught a glimpse of him whizzing by with a pile of papers and canvases. He's the resident art teacher and carries on the tradition of being eccentric. He may be intimidating at first - he's either gentlemanly and elegant or seem like an over-dedicated academic - but the minute you get a good look at him, you'll know he's a boy at heart. You'll probably walk in and find this skinny little paint-rag of a man leering over a canvas and looking as fixated and deranged as Beethoven - but he'll just as easily spin around, apologize and politely offer you some coffee or tea (both brew infinitely in his room).
He takes in art students by the dozens and lets them hang around his room like lost kittens while he's working (like Warhol and The Factory, just less amphetamines, more paint/caffeine). If the music alone doesn't draw them in, not counting class, it could just as easily be that his door seems to be left open longer than any of the others after the bell, sometimes off into the evening. To not only art students - but students in general - he is the encouraging, dedicated teacher you excepted only existed in movies like Dead Poet's Society and The Emperor's Club. He wants to take students under his wing and patch them up and send them off flying.
In the staffroom he's usually found tucked away by the window, sipping from a mug or messily scarfing a pastry while reading a book or catching up on marking. He's reserved and quiet when he's shy, watching people around him, but if you engage him with as little as eye contact or a few words he'll smile promptly and respond very fluidly. He's extremely friendly and could probably surprise you with how much he's learned about you just by watching you a bit. He feels a bit lonely right now on the staff, though, and could use some attention. He's a very good friend and it would delight me to show his colors. A few misguided students would be great, too. Or students that could even teach him a thing or two! Just people in general.
aesthete adrien is where to go if you want to IM with questions or ideas privately, or leave a comment or PM! If you want to know anything else about him, I rambled on in ridiculous amounts in his survey and bio.
