You had been taking care of Deku since he had been hit with a neko (cat) quirk making him have cat-like senses reactions and reflexes and cat ears & tail, you had been petting his ears when he started purring uncontrollably and his ears started heating up slightly as his face went redder and he couldn't keep his eyes open

"I-I f-feel h-hot.."

He started panting slightly as he drank a bottle of water still not cooling down
