I was wondering if in the original she actually says 彼女 (kanojo/girlfriend) or just the genderless 恋人 (koibito/lover) but she indeed says 彼女.

It's surprisingly good. I already knew everything because i had a database course in uni but it covers a lot of topics. I got the pdf for cheap once in a Humblebundle.
So she left and took all her stuff and doesn't answer her phone or any texts for three days. As much as i hate NTR but at this point i couldn't even be mad because this is pretty much like a breakup. I have absolutely no idea what Kotoka is trying to accomplish.
