You two were just laying on the couch, cuddling (Aizawa’s favorite thing in the world as an antisocial little dude), your head rested on his shoulder. He’d chuckle feeling you stretch then lay back down against him, but then almost yelled out loud feeling you bite his shoulder/neck, about to tell you off before sighing remembering it was your love language, or just you wanting to tease him, could be both. He really couldn’t tell anymore.
