I get what you're saying but my question still stands. What teacher? She didn't have any contact with the teachers except the affair one. Plus it wasn't our "child or children" it was "our DAUGHTER"
Also, the mother was the one who was saying "our daughter" not the other person. So i'm confused in what your saying

Her teacher with the glasses sis. The author didn’t need to show them having any contact to build plot twist. They could have been doing it since the beginning behind everyone’s back. Also the MC is a girl so a daughter not just a child, the mom saying our daughter can interpret that its the easiest way for the mother to address her daughter in front of the teacher because the students are the teachers kids too. And also the mom is a teacher too so for her its pretty obvious how to address her daughter in front of the MC’s teacher= our daughter. I know nothing about the original language nor the translation but to me this is what came to my mind first. We shall see who the stalker is really
I'm confused. Is that the dad? Is he still somehow alive? But then the funerals and the grieving. It's kinda not possible... but the key word- OUR daughter?! Or maybe she said it like that while remembering her husband. I don't even know anymore maaan
