It is as you say, of course, but, I think it's just that the character's own mental state is rubbing off on us readers... ┑(￣∇￣")┍
I mean, the seme honestly seemed a bit of a drama king because the betrothal thing had not been mentioned until now (we heard there was a girl but not about an engagement).
That was the writer's trick. ;) Lure us in without facts and then, BAM! It was left out on purpose. From the beginning it was just straight to the scene of his capture. Slowly the facts are being fed to us. It's to keep us intrigued because we know manhwas lately are all about the kidnapping and smex trope...Something has to be different to be stand above the rest or at least compete successfully. Some people are already saying they're bored with this one. I guess too much non violence.
Hmm i think itsmore of a plot hole. The marriage wasnt revealed in the dramatic way that most intentional reveals are done. Evenif it was intentional it was poorly executed. Im pretty much bored with it because the story is all over the place. It didn't focus on the kidnapping much, and their past isnt revealed to us in a way that we can connect to. All the story elements and pretty much half baked and flat.
That's why it works for me. ╮(￣▽￣)╭ It's different from all kidnapping manhwas out there. No violence or rape! I am grateful. I like that their past is being revealed slowly and tidbits like him being engaged too. I guess we just don't like the same stuff. That's okay too. It doesn't always have to be flashy or too dramatic. I dig it and the characters especially the seme. (▰˘◡˘▰)
I don't know why people are confused. He "kidnapped" his best friend because he was in love with him and he was betrothed. Dojin doesn't "remember" the girl because it represents she no longer holding his interest, Soogyum does. (▰˘◡˘▰) Gyum doesn't think his love will be reciprocated and is trying to salvage whatever's left. Or perhaps he cannot bear the platonic status quo but he is willing to try for the sake of not losing him completely. Gyum just can't face him at the moment. It's not stockholm syndrome folks. At least I don't believe so because of the circumstances of being close friends for so long.
