So I was just casually browsing the forum as I often do, and I happened to check this thread. And then I glanced down at the date display on my computer (obliviously ignoring the time) and saw that it's now the 13th!
...But then of course I took a proper look and saw the time: 01:30 (or thereabout) at the time of checking. For a none too brief moment, I thought the next update had been released and I'd simply "missed it" up until now...but I quickly realised it was just past midnight here and it will be another 15 to 20 hours before I will see today's update...

I would think it would be whenever they have their weekend getaway that it happens. She will be away from everyone else and have to confront her feelings on the matter.
Also, twins and such have a higher chance of having twins so looking at the MC's luck, he just got 25 daughters in one go if the quintuplets were natural.
