[Monochroid] Hitonomono （黑发魔女篇） (ai翻译)

https://nhentai.net/g/463296/ is the English version, though translation is pretty shit

I remember reading this before I think it was something about how the wife planned it all to have her husband stolen so he could act more loving and whatever to her out of guilt and the thrill of it all

What did she see on her phone??
