wah, that was hard to answer.
when it comes to people, no one can box them and tagged it with one word as if they are all the same.
maybe some people yes, some people not, maybe some people really have genuine feeling and loves each other, when the other just caught on the situation and decided to go easy on himself/herself then adapt with the environment. and maybe there are people who just so fucked up and don't care what happen as long as they can life, they keep living their life.
I think it just depends on which character you're talking about. Some characters doesn't know how to express their feelings in a way that most readers like and so they used brute force to express it, which usually results in rape. But it's not like they do it because it's fun or enjoyable or anything, it just like they had a rather twisted way to show it. They just don't know how to express their love gently or just staight out tell their partner about their feelings and because of this, they resort to violence.
On the other hand, in the other group, these characters are characterized as sadists and only seek pleasure in sex, enjoying torturing their victims. And in this case, no genuine feelings are involved.
The feelings come from abuse and manipulation. The captive mistakes kind actions from their captor as sincere kindness, when in reality it's only used so the captive thinks that. If the captor talks about how previous bad experiences led to them kidnapping, then they're playing on their captive's sympathy and empathy. They may talk about horrible things that they went through that never actually happened, just to make their victim feel worse for them.
If a normal person is nice to you instead of beating/raping you, that's expected, because kindness is a basic human decency and beating/raping people is messed up. But the victim is so accustomed to being beaten/raped that small acts of kindness seem major, which is how the captor takes advantage of their captive.
The feeling are "real" as it is what the captive feels, but it is not true love. It's the human psyche coping with trauma.
You can obviously enjoy works that involve Stockholm syndrome leading to real love, but it's very unrealistic towards real Stockholm syndrome and the factors that go into it.
i believe that stockholm syndrome is based upon the victims psychological trauma and becomes dependent on their capture, it is hard to say if they actually develop real feelings of love, but i do believe that based on the situation they become dependent on eachother and it leads (or develops from) the sexual relationship and tension created between the twp
as they are classified as a psychological phenomenon, does this mean that the ppl involved dont have genuine feelings?
i know how a lot of ppl dont like mangas abt a captor / abuser and a hostage / victim who fall in love with each other. but i personally like the romance. and i feel that it's unfair to judge them just bec they fall in love in an unusual environment.
this is just my opinion, and id like to know what other ppl think abt this.
