기준&혀영!
It just reminds me of Monica and Chandler, also my favorite character from Friends, who at first, started just playing around until slowly they fell for each other and decided to keep their relationship also a secret. Until one by one, their friends discover their relationship, first was Joey and then Rachel and then Phoebe and last to know was Ross, Monica's brother. In Hyeyoung & Kijoon's case, it was Suyoung, Byungjin's wife to get to know first and then Byungjin. And they were okay with it.
And in their case, I don't know why they keep hiding it but maybe because if Hyeyoung's parents find out then they will be pressured to get married and maybe 빨리 빨리! Yep, quickly. Isn't it just typical of korean parents to have their kids get married of especially if the son or daughter is nearing 30 or lest above 30, and in that case Hyeyoung is already 39 and Kijoon is just years younger. But what they have is not yet Love. And there's this 'impending' love triangle with Sanho that makes me nervous but will be fine by me since I would have it as Kijoon-Hyeyoung-Sanho love triangle than Yeonji-Kijoon-Hyeyoung. I say Yeonji is better off with either Hyunjin or Suhyeon.
It's just that Kijoon and Yeonji doesnt have the spark or chemistry for me but with Suhyeon it's cute or with Hyunjin it's fine. Hyunjin and Yeonji can be happy too. and I'd like to see more of them together ^ ^
