Some characters in Tolstoi's books, perhaps, are ASP
Varenka from "Anna Karenina"
Sonya Rostova from "War and Peace"
Good-natured persons, overshadowed by other characters;
Poor and alone in the world, with lack of money, and lack of social skills. They also do not marry, never.
Both Sonya and Varenka have a "ASP" situation. Varenka fancies a guy, Sergei, he fancies her, they go out in the forest for mushroom picking, and they come back - and nothing. They want to talk about important things, love, children, but they only utter words about mushrooms. Here's part of the text:
-------
Sergei Ivanovich sighed and made no answer. He was annoyed that she had spoken about the mushrooms. He wanted to bring her back to the first words she had uttered about her childhood; but after a pause of some length, as though against his own will, he made an observation in response to her last words.
"I have heard that the white edible fungi are found principally at the edge of the wood, though I can't tell them apart."
Some minutes more passed; they moved still farther away from the children, and were quite alone. Varenka's heart throbbed so that she heard it beating, and felt that she was turning red, and pale, and red again.
To be the wife of a man like Koznishev, after her position with Madame Stahl, was to her imagination the height of happiness. Besides, she was almost certain that she was in love with him. And this moment it would have to be decided. She felt frightened. She dreaded both his speaking and his not speaking.
Now or never it must be said- Sergei Ivanovich felt that too. Everything in the expression, the flushed cheeks and the downcast eyes of Varenka betrayed a painful suspense. Sergei Ivanovich saw it, and felt sorry for her. He felt even that to say nothing now would be a slight to her. Rapidly in his own mind he ran over all the arguments in support of his decision. He even said over to himself the words in which he meant to put his proposal, but instead of those words, some utterly unexpected reflection that occurred to him made him ask:
"What is the difference between the 'birch' mushroom and the 'white' mushroom?"

So nothing comes from it
