There was a thud! against the glass windows of the classroom door. A familiar one. No one jumped at the sound. A few bored but curious heads looked up, but one glance from Aizawa had them turning back to their books. It wasn't as if this was a new occurrence.
Aizawa stared at the windows, face expressionless. Mic grinned even wider, waving enthusiastically. He pulled his face from the glass, hands moving quickly as he signed, ending with a question, eyebrow raised.
Aizawa thought for a moment, then nodded. Mic responded with a thumbs up and another grin before heading down the hall, whistling.
Aizawa turned back to his class, frowning at the students who had glanced up during the exchange.
They quickly looked back down at the papers, pencils moving far too quickly to actually be writing.
Mic stopping at the classroom windows was a common incidence. After the first month 1-A would just watch in quiet fascination at the faces the Voice Hero would pull at their teacher. Most of the time Aizawa would simply ignore him. There was an occasional nod or shake of the head. And very rarely Aizawa would respond to Mic's enthusiastic sign language with a few curt sings ones of his own.
(Mineta swore that he once saw Aizawa flip Mic off. It had happened during an exam but no one else had seen it, so it was dismissed as rumor, much to Mineta's annoyance.)
(He had flipped Mic off. Midnight had no sympathy when Mic complained about it to her.)
Mic nearly jumped a foot as something hit the classroom window from the hall. He glanced at the students briefly, but they hadn't reacted. Looking to the window, he saw Aizawa, nose pressed against the glass, a wicked a grin across his face. Mic squeaked in surprise. "Eraser!"
Never – in the fifteen years that he's known Shota, when they were students or after they became teachers – has he returned Mic's favorite hobby of surprising him in class.
The students had looked up at the sound of the Mic's astonishment, but by that time Aizawa had gone. Completely out of sight of the window, probably had fled the hall as well.
Man could move like a ninja when he felt like it.
"Shoootaaaa," Mic whined as he entered the teacher's lounge, immediately spotting the sleeping bag. "That was mean!" He dropped to the floor in front of him, legs crossed. "They were in the middle of an exam!"
Aizawa smirked. "Couldn't get them to focus after you screamed?"
"I didn't scream." Mic huffed, turning to lean against Aizawa who grunted at the additional weight. "We'd all know if I screamed. No, they just didn't believe it was you – they got into a huge discussion on who it could've been instead. I'm their teacher, Shota! They should've believed me!"
"Serves you right. I'm surprised my window doesn't have a permanent imprint of your face after the last ten odd years."
