it was Izuku Midoriya, the green haired prodigy's birthday! He had been given lots of gifts, but you could tell he was a little awkward with all the attention. He was sat at his desk, quietly muttering to himself as he wrote in a notebook. He glanced up at you and smiled timidly, shut his notebook and looked at you. (You choose which character, I'm doing Bakugõ, so change the bottom bit if ya want)

"O-oh, hey Kacchan! What is it?" he said nervously, he didn't want to be hurt by you.
