Hmm, that’s a pretty interesting way to see it. I never thought of reading fiction like that, I used to read only because it was fun. You’ve really broadened my horizon today.
When you say, "I read fiction because it makes me happy," that's when a symbolic contract occurs. You seek fiction that entertains you, and the author provides fiction tailored to your tastes. Fiction entertains you because you've surrendered yourself to the author to please you.
