Yay, glad to see this series again!
So, here's an interesting detail: Kudou's age changed but Kujirai's didn't. During the flashback in chapter 9, when they first meet, Kudou says he's 30, and Kujirai says "so two years younger than me". Now Kudou is 34, so whatever happened to the old Kujirai was in the past 4 years.
Kujirai on the other hand is consistenly referred to as being 32, in every appearance, past and present. So the point where she was cut off from her past (for whatever reason) happened within a year of her meeting Kudou.
