In my father's house, there is a dirty old man who I don't really like. The moment I met him, I was filled with disgust. "I want to run away, I want to run away..." The dirty old man's breath stinks and he smells sour, he's the complete opposite of my father... but once I get used to him, it feels good... Even though I say I don't like it, he touches my body, and it feels creepy yet good... A secret friendship with the dirty old man. "Mom and my little brother Yuu don't know... I'm sorry... but I love you..."
