It's not that we "enjoy" it, it is the plot. He knows he's kinda being "brainwashed", hence, he stated he is losing his sense of reality, he is a self aware king tbh~ maybe that's exactly one of the point why Zhenya put him in a desolated place, the pain and pleasure he is giving him, the mind games?? You see, the plot.
Dw just incase u missed the whole point
1. Taekjoo is a national spy. A threat. Just cause he's bby ghorl doesn't justify his actions. He trying to sabotage a whole country guys...
2. What Zhenya is doing is practically "torture". U either get this special treatment or have him in a basement and have his fingers/nails/scalp shaved off his body
3. Teakjoo aint having 'feelings', what he has is gay awakening. He's beginning to 'enjoy' the torture
4. It's Zhenya catching feelings, so no there's no stockholm syndrome, it's the other way around
5. All this "torture", aka rape for y'all, will end after getting out of Russia, cause after all again.he.is.a.national.spy

Only me don’t enjoy the continuous r ape? I hate it and wdym he’s growing feelings bruh he’s being brainwashed pretty sure if the Russian was not awesome everyone will think the same Urgh
