A chapter with such a charming foreigner
deserves an appropriately romantic song:
Moscow Nights
(sung by Ketty Lester)

Here's the original Russian version:
(sung by Anna Netrebko and Dmitri Hvorostovsky)

EDIT:
For good measure, here's the Japanese version:

When I listen to that version, I can easily imagine Sonya
being serenaded by her male classmates and admirers.

EDIT 2:
For extra good measure, here's the Chinese version
(which is exceptionally pretty):

EDIT 3:
I just discovered this lovely Russian song:
Dark is the Night
(sung by Zere Amirbekova)

Here's a more contemporary version:

EDIT 4:
I discovered another lovely Russian song:
The Night is Coming

Here's the Nightcore version:

As you say, the translation is outstanding. Using Microsoft Bing,
I verified some of the Russian words, including Ñперма (sperm).

EDIT:
"ПотрÑÑающе!" (page 24, panel 1) gave me some trouble.
After experimenting with Bing, here are my (odd) results:

ПотрÑÑающе! = How thrilling!
"ПотрÑÑающе! = "Awesome!
ПотрÑÑающе!" = Awesome!"
"ПотрÑÑающе!" = "Amazing!"

I'd probably choose "Awesome!" to reflect
the way Anglo-American teenagers speak.

I'm not fond of the "male teacher / female student" trope,
either, but I give this chapter a big thumbs-up, if only for
the beautiful artwork and the charming, adorable FMC.

I tip my hat to a fellow connoisseur.

Urgh that's so bitter with some sweetness at the end that I'm really conflicted for the vanilla tag . I mean it's probably half rape the boy before so .... uuuuh and she was so cuuuute !
