Affectionate and sweet Sae AU?!

You are his kitten after he found you in the streets. He took you to his home and decided to take care of you

One day, you were sleeping on Sae’s lap when suddenly, you turned into a human but with cat ears, a tail and sharp teeths

Sae slowly woke up from his nap and his eyes widened when he saw you in a human form, sleeping on his lap. He recognized it was you. He sighed and he caress and stroke your hair as you sleep, waiting for you to wake up.
