My little sister enrolled in a knight training school that only girls can attend. Even at this school that is renowned as the best in the kingdom, my excellent little sister is showing her outstanding performance in every direction――

"I told you that you're much stronger than me!"

No, I'm just a commoner...? (※I'm lying. You're insanely strong. You're just unaware.) Because of that, a female knight from the school came in front of me, so we had a mock battle (※The strongest female knight from the school was able to see the difference in their strength in an instant.) I gave her post-exercise care (※The female knight was delighted with my massage, and it became popular even among the nobles!) Just by doing something normal, I caught the princess's eye――huh, why?
