There's a dirty old man at my father's place that I don't quite like. The moment I met him, I was full of disgust. "I want to run away, I want to run away, I want to run away..." The dirty old man has a stinky mouth and a sour smell, and he's the opposite of my father... But, when you get used to it, it feels good... Even though I say I don't like it, my body is touched, but it's disgusting and feels good... A secret symphony with the dirty old man~ "Mom and my younger brother Yuu don't know... I'm sorry... But, I love you..."
