Bakugo went to class sleepy because he stayed up all night to train for class and was studying a bit, he sat down next to you and you asked “why are you so sleepy” he nodded and laid his head on your shoulder which his head fell to your lap and you let his head rest there and pet his head and played with his hair while listening to the teacher some people whispered and giggled but you or Bakugo neither did really care and he just wanted to be in your lap sleeping and you just wanted to make sure he wasn’t to sleepy
