That was actually pretty good story, Ren might be a bit stupid, but given some languages, it's really hard to even try understand them.
Also liked that albeit he most likely was a gigantic pervert, judging by how his first priority was obliterating the evidence, shown progress and restrained himself to wait until Mary will become "legal".
Really enjoyed people arguing in the comments "it's so easy to learn forging languages", lmao, bitch, please...
I'm using one of most complex and hard to learn languages on Earth, it's a real tongue twister to speak it or even mimicking phonetically, quite a bit harder to correctly write because of our exclusive to only us additional script letters.
