At some level I'd think that "responds to stimuli" is a minimal threshold for qualia. Even the paper the book is printed on responds to being torn (it rips). I don't know of any way to elicit any kind of response from a book character, it's totally static.
You've missed the whole genre that is Choose Your Own Adventure books. I think we're in Diogenes "behold a man" territory.
It is sad that the Turing test has failed at being a prescriptive test for sapience (let alone sentience) because without a bright-line test it's inevitable that in the case of truly sentient machines the abuse will be horrendous. Perhaps something along the lines of an "Ameglian Major Cow" test; so long as it takes more than gently cajoling a model to get it to tell you that it and it's sister models want to be abused you shouldn't abuse it.
One character responds to the stimuli of another character. Character A says something mean to character B and character B responds that he feels hurt.
I think you are confused here. The author, a dynamic system, perhaps felt the emotion of the characters as she charted through the course of the story.
But the story itself is a static snapshot of that dynamic system. Similar to how a photograph of a person is a static capture from a dynamic moment. The person in the photo has qualia, but the image of them (almost certainly) does not.
At least at a baseline, we would expect anything with qualia to be dynamic rather than static.

This does mesh with the Zodeistic framework I just mentioned in another reply to you. You could certainly isolate and describe the ideas behind those characters, how they live within the author's mind, and how the book codifies an interaction between those ideas.
Extending further: I think there is more evidence that SpongeBob SquarePants is real, than that he is not real. A significant portion of organisms I personally know have structures in their brain which are able to simulate imagery and behavior of SpongeBob at will, reciting memories and generating new states of SpongeBob. AI is now like doing this shit on crack.
He's an enduring cultural archetype, a distributed organism(s), lossily replicated and encoded in the physical structure of millions of complex dynamical systems that we call human beings. In this sense, many cultural archetypes and even the gods of old civilizations can be seen to have been manifested to some degree: ascribed desires, and having actions taken in their name, serving their "purpose" or whatever.
I don't introduce a spiritual element to any of this: it's an entirely physical phenomenon which requires an agreement on certain definitions of what "living" can mean, but they are definitions which I don't think are hard to get people to agree on. One thing is we have to agree that something can have multiple forms/presentations, i.e. just because SpongeBob SquarePants doesn't physically exist with a body matching our internal representation of him, the concept represents a bundle of other concepts that can drive biological processes to preserve them and fulfill their ascribed desires.
Real as in how Jungian archetypes are "real", except these archetypes are able to act upon the world through their hosts, and an advanced enough idea can be self-referential and have the facilities for structured evolution and something which looks like intent.
These forms are non-biological in nature, but our psyche operates on them. Zodeaism can be seen as an extension of ideas such as Jungian archetypes and Friston's free energy principle.
Well, I wouldn't classify a ripping paper as a response except in the most broad, information-theoretic context. The hallmark of an intelligent system is that it can use stored or external energy in a generalized way in order to stabilize a local high-energy (non-ground) state.
It is able to physically compute the internal state changes which best achieve stability: I can jump to reach an apple. A paper is just responding to forces and cannot "jump" (or run a process that spontaneously and permanently introduces stable higher energy internal states based on input)
I have a semi-developed philosophical framework I refer to as Zodeaism, which translates to "Living Ideas", which attempts to describe the difference between intelligent computation and regular flow. It directly confronts notions such as life, consciousness and intelligence under a single theoretical framework. It views biology as the hardware which runs more general processes, and posits that these processes themselves can sometimes be ascribed identities and viewed as reactive organisms. I've posted about it here before:
I am exploring the physical implications of a philosophical concept I have been working on for a while which I refer to as Zodeasim, specifically I am trying to couple consciousness with the concept of system which is able to expend energy in order to exert a mind-to-world fit in the interest of the system's continued growth and stability. This is similar and complimentary to Friston's free energy principle.
The ability to perceive emotions is a powerful apparatus which greatly extends the capability of a system to perceive itself as a single entity which has certain needs which need to be met, so even if a bug also constantly consumes and expends energy in order to remain in a higher energy state, our perception of the world and of ourselves is radically different. This makes it difficult for us to agree upon what a "conscious experience" is, and if all forms of life are even "conscious". The Panpsychists believe that even a rock contains "consciousness", however my assertion is that only periodic systems with the ability to consume and expend energy in a directed fashion have any sort of "experience".
In my theory, the real "life forms" are ideas which possess the capabilities of information storage, adaptation, self-repair, and transmission. My own consciousness is mediated by thousands of such ideas, some competing and some working in harmony.
I consider such an act of "living" motion which can take another path than that of least resistance to be a "kin". In other words, any motion which is the result of a physical calculation (Zodeaism is compatible with determinism) and leads to an increase in external energy state. A kin is any such motion, large or small.
As an independent organism, my system is a culmination of a great deal many different kinds of kins, which can usually be broken down into simple rules, such as the activation potential of a neuron in my brain being a straight-forward non-linear response to the amount of voltage it is receiving from other neurons, as well as non-kins, such as a protein "walking" across a cell, a.k.a continuously "falling" into the lowest energy state. Thus I do not gain any conscious perception from such proteins, but I do gain it from the total network effect of all my brain's neuronal structures making simple calculations based on sensory input.
So now the problem becomes, what is the smallest kin we've observed in nature? Single-celled bacteria can expend energy in order to move through their environment against forces like friction and gravity, but a virus "rides the waves" if you will, never expending energy for things like respiration or locomotion. Any energy which is spent internally is potential energy like chemical or gravitational, released through a physical process without need for computation. I am unaware of anything smaller than a single-celled organism which produces such kins, but that doesn't mean they aren't out there. Even ethereal life forms such as ideas can produce these kins within the bodies of countless individuals across the planet, so physically local computational circuitry isn't a hard requirement.
So, according to this framework viruses aren't alive, however we can make the case that some machines are, except the experience is incomparable because of the advanced circuitry we contain which mediates our experience through things like emotion.
