I mean... not really. Lots of visual novels (like all otaku media) are just stealing/repacking concepts from more competent works. They're only beloved by a market that has no interest in literature.

The Treaty of Versailles was only "harsh" if you ignore context.
The Germans themselves first imposed the brutal Treaty of Brest-Litovsk (March 1918), 15 months before Versailles. Russia lost 1 million sq miles (Finland, Ukraine, Poland, Baltic States, and parts of the Caucasus), half of its industry, and a third of its population.
As for the West, Germany's Chancellor Bethmann Hollweg's September Program imagined just as harsh a treaty for France after her (hoped-for) defeat. In addition to confiscating border territories, they would impose a crippling indemnity. Belgium and Luxembourg would also be absorbed into Germany.
The Germans lost, so their dreams of conquest never came to pass. (And, after their surrender, they were forced to give up their Russian territories.)
The truth is, after four years of horror, whoever won was going to try to stick it to the losers. Politically, it would have been impossible to tell citizens who had suffered for those years, "Hey, we're now going to go easy on our enemies!" As it is, Versailles was kinder to Germany than Germany was to Russia (and kinder than Germany probably would have been to France).
my internal calculator says there's a 95% chance she only says this because dostoevsky is russian and any mention of russia activates the self destruct feature in the logic part of ukrainian brains
