Good heavens do I appreciate having all of this uploaded at once and not having to wait after each of these chapters. Like, this isn't a resolution, but it's a lot more of one than it would have been at any other point!
'it was all a test' sounds too much like 'apparently I did the wrong thing and I can't have done the wrong thing so I'll insist there was a context that made it the right thing'
this is definitely a lewd joke taking advantage of a euphemism in Japanese (which is hardly ever used straight anymore; daku as 'hug' has been replaced with dakishimeru to avoid confusion, but Fern used daku)
