I don't think that just making up names for a couple automatically make them kookwan. Fans do it for fun like me, i give almost every couple I like a nickname. Nowadays people on judge from the outside, if they think this couple look hot together, they're a kookwan, so I also don't know the real kookwans. For newbies real Kookwan couple is most definately Bargie, I really didn't like that couple but after seeing parts of Wayupak Montar My mind was blown. Also their off-screen friendship is so strong! For Older generation, most definately KA&Num Kob i don't want people to judge them for their looks but to look at the acting skills. For KA even the media knew there was something different, like a spark, when they work together. I use to judge kookwans by their looks (ex.Ateam) but gosh I am crazy for JLR. This is all... I hope no one gets offended Na Ka.. my personal opinion <3
