Former wife Nanako. Older than me, so-called sister's wife. He did everything and wrapped me up, but I misunderstood and had an affair, which caused me to part with Nanako. After that, I remarried my wife, who was an affair partner. However, if it doesn't go well, my wife now sees me only as an ATM and is oppressing me as a demon bride. At that time, when I met my ex-wife Nanako again, I fell in love with my old habit. A flower bloomed in an old story, and when I noticed, I was holding Nanako.
