I've been married to Tsumugi for a few years now. Today, Tsumugi still makes me a bento lunchbox just like when we were newlyweds. Our relationship is just as happy as when we were newlyweds. As I enjoy these happy days, my junior colleague Himori boasts that "housewives in their third to fifth year of marriage are the easiest to seduce," and I blurt out that he should try to woo my wife... I invited Himori to my house and made up an excuse to leave my wife and I alone for three hours. After some time passed, I returned home, but I completely believed what they said when they said nothing happened...
