Not seen since ch 289 and referred to as Ichijou-san then, it took a bit of figuring out that this Kaho IS Ichijou and now Hisao' s new wife (when?) and he has not remarried his 1st wife. That would have made his 1st wife 12 years old and 17 years younger than him when she had Rui (!) Which made me think that might have let them be happy with Rui marrying her teacher at 17 while still in HS.
I suppose with Japans population crisis, anything goes.
