its like pavlovs theory but with sex

if a particular stimulus in the dog's surroundings was present when the dog was given food then that stimulus could become associated with food and cause salivation on its own - from Google. If in simple terms, it is like X person doing sex with Y person under certain conditions, so when X and Y breakup, X person will be conditioned in such a way, that if they do sex with Z person, they will remember those certain conditions when X and Y did sex and might get hard. But this only happens when repeatedly done in the same exact way.

I'll try to explain
Pavlov's theory is a conditioning in where stimulus or a signal is followed by a reward.
For example:
I am exposed to food packaged in a plastic that crinkles when I open it (chips, biscuits, etc.)
So now when I hear a plastic crinkle (stimulus / signal) my mind instantly registers it as food (reward) because I'm used to seeing food whenever I hear that sound. My first thought whenever I hear it is "that's food".
In conclusion, my mind automatically associates food with that sound because I am exposed to that condition.

new update new reminder that if you dont like the manga or find the age gap creepy then youre free to go and read something else instead of wasting your energy yelling at people that the uke is a pedo or that the author is weird for this manga. commenting stuff like this doesnt make you a better person and doesnt imply that you have a higher moral ground than the rest of us who likes this manga. go away please and thank you
