This was a date. Just a date. There's no denying that, at least. You could call it a friendly date, but it is obvious that she's starting to like him more and more lol.
A noble who doesn't know how a smartphone or what apps are may seem strange, but it does make sense if she was sheltered. Villers probably never really needed them either, since she seemed to have lived a relatively sheltered life. It is pretty cute that she ended up buying the same model of phone as Katagiri. She really values his opinions.
Villers first friend is Katagiri, and her first phone friend is him too! I'm sure he'll be her firsts for a lot more things to, haha.
I didn't expect Katagiri to quote the Bible. The verse she used was actually used pretty well in context too. Something like a phone feels wasted on her, because she doesn't actually know how to use it.
There's a phone with 2TB storage?
I doubt, at least not heard of a phone with quite that much internal storage. Even the largest microSD currently is only 1,5TB...
I have a computer with 1.5 terrabytes of data, and I can never get it to full space. A phone does not need that much space.
