Yeah I'm not a fan of these "stockholm syndrome" stories...
In my case, it's not the Stockholm syndrome that's the problem. In fact I very much enjoy psychological themes in manga and webtoons to the point where I would probably reread it even how mess up it is(cue Killing Stalking, though I still don't have the courage to reread it for now but—).
The problem with this webtoon are the developments that it lacks considering it play psychological theme in the plot. You couldn't feel anything at all. The mains' relationship is too superficial that you won't be able to sympathize with them.
It seems like I'm not the only one who doesn't want them to end up together.
