Taking Care of My Knightly Sister, and Somehow I Got Noticed by the Queen

My sister enrolled in an all-girls knight academy. She excelled at the academy, which is renowned as the best in the kingdom–

“I told them you’re way stronger than me, brother!”

Uh, I’m just an ordinary guy… (Actually, that’s a lie. My brother is insanely strong. He just doesn’t realize it.)

Because of that, female knights from the academy came to see me, so I had a mock battle with one of them (the strongest knight in the academy instantly realized the vast difference in our abilities).

I also took care of them after exercise (my brother’s massages were a huge hit with the knights, and even the nobles started talking about it!)

Just by being myself, I caught the eye of the princess–wait, why?
