That's the thing : in japan (and not only there, but as the manga intend to adress japan in particular, I'll focus on that), women are expected to start a family during their youth, only working until finding a husband so they can become housewives. A career minded woman is frowned upon there, because she's seen as "not fulfilling her role as a woman".
Frick, there's even a slang for unmarried women past 25 in japan : "christmas cake" because after 25th of december, nobody want a christmas cake anymore. Let's not forget of the many lesbians forcing themselves to marry and have kids just because of the social and peer pressure put on them. Simply put, in japan, a woman that has not started a family before 25 is pretty much considered to have wasted her life. Another reason why "shotgun marriages" are a thing there.
Sure, this chapter might be bland compared to the whole tournament and revenge thing but it's still in line with the intent purpose of the manga and still making a heavy parody out of it, so people can't simply go as that guy in the chapter and deny what's going on.
