with no hobbies, just commuting between home and work. my wife and daughter think i'm useless, and i'm a typical burnt-out middle-aged man. as i left for work, my daughter pushed me away at the doorstep, saying i was in the way, and i fell down. there, sakura, my daughter's classmate, was staring at me with a blissful expression. sakura was a woman who got sexually aroused by burnt-out middle-aged men. from that day on, sakura and i began our sweet and dirty affair.
