Shuraba Marugoto Isekai Shoukan: Danna wa "Yuusha()", Uwaki Aite wa "Seijo"-sama. "Shufu" no Watashi wa Fuyou desu ne?

I'm Nadagi Yu, a 27-year-old office worker in my late twenties. Married, no children. One day, when I returned home to retrieve something I forgot, I caught my husband, who was supposed to be absent from work due to poor health, cheating on me. And the other woman was a soft-spoken, carnivorous girl from my company. They both started blaming me, telling me to get out of the apartment I was paying rent for, and doing whatever they wanted... Just when I was getting fed up, I was summoned to another world, complete with this whole mess. According to an old man in the other world, my husband is a "hero ()," the woman he's cheating with is a "saint," and I'm apparently a "housewife." Since it seems "housewife" isn't the name of the game, I'll just do as I please. And so begins the other-world life of a cat-loving, baby-faced, sharp-tongued "housewife." Don't underestimate me just because I'm a "housewife"...!
