This honestly feels a bit odd calling it NTR without including Touma and giving any form of response.

While I haven't read that far into the story (mostly mangas), has Touma ever responded to her feelings (and has she ever gotten far enough past her tsun to dere infront of him?) Even with their friendship, I can't recall him going out of his way to meet her when shes not directly involved and at an incident hes resolving, its when they bump into each other or she seeks him out. With his complete absence in this story, and not even sending him video messages of this, isn't he just gonna notice in a month or so he hasn't bumped into her lately?
