Updated with improved translation and scanlation quality.

First time uploading. Let me know if there are any issues. Complete amateur at this. Got tired of waiting for others to do the dirty work.

I'm almost inclined to add the "Yandere" tag. The MCs girlfriend is something else indeed.

The typesetting needs work overall. The font choice is questionable, the line breaks are iffy at best... generally just a bunch of first-timer mistakes. The cleaning looks fine from the glance-over I gave it, and I can’t speak towards the translation as I’m not a translator.
If you want to improve at this, go to the e-hentai forums and find the translator’s cove. There are guides that will help you improve your typesetting, and you can talk to people who are experienced and willing to help. We can always use more people on the job, especially those who have the time and skills and are willing to learn.

So my advice would be- go to the forums, talk to people, re-do this piece, and re-upload. It’d be appreciated by all!

This was acceptable for a first try. However, aside from the rookie typesetting issues, there are also a few translation errors here and there. Most blatant of them being getting the names wrong:

悠斗 = Yuuto
小夜 = Sayo

Also you seemed to not to decide on how to translate Sayo's name, she went from Saya to Sayo and then Sayu over the course of the story.

Anyhow, thank you for trying. It would be great if you could have someone else QC your script and then release a v2 if you're up to it. If not, then I hope someone else picks it up. I'm honestly kinda surprised no other translator/group has picked this or any of the author's other works up, given that his first work was decently popular and even got fully translated.

Can you do part two as well

Thanks for the feedback. Probably might do part two if there isn't any other major effort. Thinking of just getting someone else to do the scans. If there's anyone that just wants to take the script and just make a v2 with fixes to my typesetting and other mistakes then feel free. Don't feel like going back to make all of those tiny corrections.
@セージ - Yeah I noticed the mistake with the names halfway through... From what I had seen, Haruto was a common male Japanese name and I just rolled with that. Then I saw in the furigana in part 2 and realized that I effed up.

I would love part 2 as well, it looks like the even better one

Why not chiya, 小夜

Take any one page, zoom in, and compare it to the original counterpart. You will see the lost of some details; a small blur is noticeable especially around straight lines adjacent to a white background. I'm no digital artist, so I cannot give more details on how to avoid it though.

Gallery updated. Special thanks to Moozumi for fixing my shite mistakes.

The fact that none of them seem even a little concerned about what happened to Ayumi does suggest that they're all kind of terrible people, huh?

If it’s not too much to ask, could we get a translation of the sequel?
