My Genius Little Sister Can't Do Addition

“What’s three plus four?”

The girl in front of me counted on her fingers and answered timidly, “Six?”

“...Then what’s four plus three?”

“...Five?”

I patted her head. “In a way, you’re even more of a genius than before.”

Don’t worry. Big brother will definitely protect such an adorable little genius.

This is a heartwarming story about redemption. I hope all love can be this fearless.

The fantasy category was a mistake. This is an urban school story with no fantasy, magic, or sci-fi.
