"It's been about three years since my wife passed away, and since then, I've been living alone as a parent and daughter, but I don't want my daughter to feel lonely just because she's a single parent, so I've been working hard in my own way. One day, when I was watching TV with my daughter as usual, I superimposed the image of my late daughter-in-law on my grown daughter's body, and since that day, I have been having sex with my daughter, and my love for her has increased more and more, and I have bought a camera to record my daughter's growth. I was planning to watch the video after my daughter got married, but I posted it because I thought it would help pay for my daughter's education." (Father's story)
