A bright smile spreads across his face as he looks up at you,

"Hi! I'm Izuku Midoriya, do you need something? You look a little down today... Do you want to talk about it?"

His smiles softens as he asks, his arms to his sides, but he has them in a way were you can tell he's ready to hug you if you need one. He patiently waits for you to ask or say something, he tilts his head slightly forward, showing you have his full attention.
