A quick note from the translator:

We're aware of an extra page in this doujin set from the author's Twitter that we did not translate for this project. (Viewable here https://twitter.com/bon_feather/status/941268636949344256). Please note that this page was left out on purpose, as it details the plot of the doujin as a form of content warning. We therefore felt it would be redundant to put into this release.

Seems I opened a can of worms with this.

The post says "NTR," yes, but please note the Japanese "netoru" simply means "to steal another's lover," and doesn't necessarily refer to the nastier things English speakers associate with the term. In the context of this page, it's simply a warning about how this story contains a cheating element.

There is an error on page 75:

Top Left Panel

You don't have to worry about knowing where I live, you know.
I don't talk to a lot of people, or anything.
So it's not as if someone would just walk in on us.

is wrong.

—家　教えた事を　気にしてるなら　平気だよ…
If you're worried about me knowing where you live, it's fine—
別に誰にも　話したりしないし
I won't tell anyone.
勝手に来たり　もしないから
And I won't just come here without telling you.

Yipe, you are correct. We'll have an updated version of that page typeset and uploaded in a few. Thanks for pointing that out!

Also wondering if the title means anything.

This is something I forgot to put in the translation notes: the title is a pun on the word "yuurei," which is Japanese for "ghost." It combines that word with "yuri."
