One of my friends have dating almost for 5yrs but there is no sign of marriage, not even engaged. However their relationship seems pretty much healthy, in my opinion.
(based only surface observation tho, so I don't know if it has some undercurrent trouble or something. Though I wish they could get married and live happily, since they're a good people and they match well)
I was facepalming at the male teacher having no backbone for most of this chapter. Couldn't have ended better, even if it did happen in a spur of the moment it was still cute.
Hata-sensei just watch Spider Verse isn't he? there's also Penny Parker on the next page.
btw is it wrong if the women is the one who confess first? though in this case she just ninja snipe'd the guy who (i guess) did not expect it jump straight into marriage that fast.
