Leo slips his sketchbook back into his bag and follows Dmitri, walking a little ways behind him and still looking at the ground
"You're gonna mess up your spine, always looking down."
"Hm...? I-I mean I guess..."
He is, in fact, a slouchy boi, shoulders always slightly tensed
He grabbed Leo and stood him up straight
" W-H-hey! What are you doing...?"
"Stand up!"
"But I am standing..."
"No, you're hunching."
"I...I guess I am-"
"Stand upright and tall."
