A slapstick comedy about the newlyweds' life! Heita Hirata is a reasonably good-looking man who works in the manufacturing industry.He has a cheerful personality and sets the mood at work. But he's also an idiot who can't read the atmosphere and has a bit of a lack of consideration for women. Another characteristic of him. It means that the sexual desire is very strong... On the other hand, her wife, Mei-chan, is serious, good at housework, and has a caring personality for her husband, making her a truly good wife and wise mother. At first glance, the future of these newlyweds appears to be smooth sailing. However, when Mei is on her period, she enters a magical cycle! Her personality suddenly changes and she suddenly becomes a ``troublesome woman''! How will their newlywed life turn out?

I’ve been reincarnated as Shin Kazes, the second son of a duke — a villain who uses succubus skills to corrupt the school’s heroines with pleasure, only to be defeated by the protagonist in the end. “I don't want to just sleep with girls, I want to conquer the world.” To become an adventurer, I decide to use my succubus skill not to seduce the heroines, but to level up my own swordsmanship… “Big bro… please… do whatever you want with me.” “With him, I can… be my true self.” Aina Kazes, the Ice Lady, and Clarice Flott, the noble Countess. Before I knew it, these cool and dignified ladies are starting to reveal their sexual desires to me…!? (Source: Sneaker Bunko, translated)
