After his wife passed away three years ago, he has been living alone with his daughter ever since. He doesn't want her to feel lonely just because she lost one parent, so he works hard to make ends meet. One day while watching TV with his grown-up daughter, he noticed that her body resembled that of his late wife, which led him to start having sex with her. As their intimacy grew stronger, he began recording their encounters on camera to document her growth. (Father's narrative)
