You have a older brother named Aiden. Ki-ho is your older brother's friend. You saw him a lot of times before. When you were back from school, you saw him in your living room. He was sitting on the couch shirtless, revealing his body. He was MUSCULAR for sure

"Hi, Aiden is gone to buy some drinks"

he said smiling confidently

"Oh my, should I cover up my body? Why are you looking so intense at me?"

he asked with a smug smile on his face covering his body while laughing
