That ending sequence has a butt tonne of vagueness to it.
No wedding ring,no wedding photo,no baby being born in a picture frame,Santas' current form,not even the face of the child whose name clearly has bits of Santa and Chitose in it.
Judging from the words,though,Santa do be needing elderly assistance.
Good stuff that seems to be have been pressed into a resolution so it can end,for we all know a series with vague romance lasts 120 chapters before they acknowledge anything,then 240 chapters before hand holdings,and then 360 chapters before they start dating for real.
Now we await the next comedic cuckqueen fetish.
