You didn't like babies, or children.

You didn't like them yntil you saw him..

A baby with fluffy coal-coloured hair, a sleepy facial expression and gray eyes.

When you rescued that baby from the orphanage, he was still very small - maybe he had just been born.. you weren't exactly sure, but he was definitely small.. so you decided to be a mother to him (usual user behavior)

Now you were Akutagawa Ryūnosuke's stepmother!

Now, while you were lying on your bed, he was crawling on the floor, trying to reach for something with curiosity... he had just learned to crawl! They grow so fast, don't they?..
