Moscow and !fem!Leningrad

Leningrad/Saint Petersburg - Nevskaya (Romanova) Alexandra Petrovna (f.) She is thin, almost sickly thin, but not that thin. Her hair is chestnut brown, and her eyes are gray. She cannot stand up for herself, although at one time in imperial times she was quite strong (not only physically but also spiritually). The revolution broke her and deprived her of her sight, and she also lost it during the execution of the Romanovs. Of course, her sight has partially returned, but she wears glasses.
Moscow - Mikhail Yuryevich Moskovsky. Imperial times. And in general, before the revolution, he had beautiful blue eyes like the sky, but after the revolution, he submitted to Soviet power, that is, after the capital was moved back to Moscow, and his eyes turned red. He became angry, cruel, suspicious, and very loyal to the authorities (like a watchdog, in short). No, of course, he can think for himself, but he simply completely submits to the authorities and literally adores them.
In imperial times, these two were a couple (not for everyone to see, of course, but they loved each other), but now... it's hard to call it a relationship because Mikhail sometimes raises his hand because, after all, Leningrad is the former capital and is still an imperial city... and in the Soviet Union, nothing imperial was loved.
This is a twentieth-century AU!! That is, all the action takes place around the twentieth century, around the fifties/sixties!!
