That deep lore dump in the translator notes was kind of like reading the wiki after finishing a fantasy book.
I bothered this time, but if people want to stay ignorant (or do it themselves) it'll save me the trouble.
I quite liked it, gives me ideas of where to go in JP if I ever visit. If you don't do it in future, though, that's totally cool! It was just really sweet to have extra context to their date.
This chapter was so adorable but I completely forgot that they're actually going out now... so it was double sweet.
