I normally dislike the "wedge" character just introduced to cause trouble, but I can't help but feel like the Librarian girl isn't particularly malicious, or there's a fairly decent reason she's the way she is. Could be totally wrong, but looking forward to seeing more as usual.
I think it's because of that one restaurant patron (I think she's a surgeon? The one who gets hammered and hits on the guy all the time) who draws porn manga. We've seen her working and talking to her publisher and it's included shots of her pages which are kinda saucy.
Blessed translator-san won’t let us die with some sexy/scandalising cliffhanger that’ll tie up our anxiety with misunderstandings and speculation. We are truly not worthy of such graciousness and mercy! 😭😭😭😭
