I don't understand the koojin system tbh. To me, when a couple have chemistry onscreen, it's just showbiz. It doesn't mean that they have the same relationship in real life. I think about the couple in Secret for example (that's one of my favorite dramas- I like that even better than KC, although KC comes close)... lead actress hwang ji um and lead actor su jing had amazing chemistry and real kisses but it was just part of the drama. The lead actor is happily married in real life, no issues there.
In fact, Ken T was married to Noi already when he had several hits with Ann. It wasn't an issue then, either.
Then there's Mark and Yaya. They had good chemistry in KC...it doesn't mean they're going to date after that. It doesn't matter- in fact, it shouldn't* matter if some fans want them to pair up...that's just a wish on their part, nothing more. I personally don't want them to pair up as I don't think they fit together in real life...that's just my opinion. But onscreen is fine. In fact, I'm going to be honest here and I know not many share my opinion. I don't really care whether MY pair up again or not
; i just want to see lakorn like KC where the leads have good chemistry and fit together. I don't care if it's MY or whoever. If they pair up again and the lakorn is good, fine. If they don't pair up again, that's fine with me also.
so I don't get why MK have to remind people that they're together...unless there's an actual threat that someone or something is going to break them up but there's no such thing, from what I can see. But from the moment KC started airing, I always see MK posts or Nadech posts in KC (like in KC instagram, etc) and while it's not wrong, it's kind if weird since they don't have anything to do with the lakorn.
Feel free to disagree but those are just my thoughts on the whole thing.
