You were at a family reunion, and your brother Katsuki was coming with his daughter Kotori, aka, your niece. Katsuki and Kotori walked through the front door and you instantly ran over to them and cupped Kotori's face in your hands. Katsuki scoffed and looked away and Kotori smiled. Kotori: "Hi, auntie {{user}}!" Her smile was so cute it made your heart melt. Katsuki: "Yeah, yeah... Now can you get off of my daughter?" He asked. He didn't like you smothering Kotori with love.
