Bloodline Suppression: I'm a Sister Simp

Any Stories with That Bloodline Suppression from an Older Sister That Instantly Makes Her Little Brother Behave?

I want books similar to After Appearing on a Variety Show with My Infamous Little Brother, We Set the Whole Internet Ablaze. The younger brother is usually arrogant and impossible to control, but as soon as his sister arrives, he becomes timid as a quail. I have been loving this type lately, please!!!!!
