Darkness 闇 : Not sure if this is what you're talking about since I've only ever taken like two coding classes and that was right after I got out of HS way back in 2008. But inside your game folder find the current version: TeachingFeeling-2.5.2\data\scenario ;
cause when I was bored one day looking at random files I noticed that the series of .ks files appear to me (and remember bare in mind I might as well be "Code Illiterate" at this point) like they might gibe you the access to the files you're wanting to edit.
*EDIT: Looking through the files again I think based on that this may actually be the file(s) you're looking for:
TeachingFeeling-2.5.2\data\others\translate\assets (Again really not sure on this but I hope this helps atleast somewhat)

Oh and also because of that I realized it atleast seems to me that my random points of non-translation may be getting set by those files. Its more or less though a non-issue (as the text doesn't seem to effect much [although I have noticed that since I told Sylvie to use "F' me," as an Idiom for "Sex" it does occur more frequently when she uses it]), but like I said I don't really know much. And since its been requested next time I remember I'll take a Screen Shot of those non-translated parts, and if anyone thinks it might help I can attempt to locate those parts in the .ks files and screen shot them as well.
P.S. And tbh its not that I'm new, it's that when I first started using this site I never once posted. It wasn't until this game I ever felt the urge or need to post. That said I do appreciate you being patient with me, and I'm sorry for making you feel like you needed to repeat yourself. I've actually been meaning to get those Screen Shots to you, but everytime I go to play, I just find myself suddenly distracted by overwhelming cuteness
