It's actually not clear if it's supposed to be connected or author just used similar looking characters.
I think in this case they might actually be the same people ,but on the one doujin they have of the teacher being confessed at by her foreign student,the teacher looks exactly like the glasses girl.
This feels like a romance VN where the protagonist is the same but each route is like an alternate reality hahaha

So if that's the case, then can the one where they have a kid be an AU where they become immortal and get to love each other forever :'(
