Errata Corrige (1990-s Arc) (смешанная)

Not your general type of time-travel Tomarry: this time it's "Tom visits Harry's timeline".
Definitely will be more mature in rating in latter chapters. Platonic relations are great too, but I'm all for good old pron. And I feel there's lack of such fanfics now in this corner of the fandom (Tomarry, Harrymort and the like), so I took the liberty.
As for the rest - I'm not sure myself where this fic goes, as I have only the beginning written and no plot yet for the later chapters this time. Also my summaries of late smell of spoilers, so I'll try to stick to the short ones.
