MC for the lady MCMC: .....let's go into detail with the previous topic, what is your ideal type?
K: Hmm, as I said just now, I like Kim Sam Soon's type
MC: Ahh, the round and chubby type.

C: Me too......
K: Hmm.
MC: Actually, Songha also likes this type.
C: Ahh!! ...I think YEH is not bad!!!

KJK and YEH are quite compatible.!K: YEH is not bad~~ Yes...
MC: Yes, yes..
MC: Ah~ but, are both of you really not in a relationship?
C: Relationship.....not yet..
MC: Oh~ wouldn't it be great if they're in a relationship
K: (This must be everyone's wishes)....
C: Previously they do meet up!MC: AH????
C: They do meet up but not in a relationship yet right?K: What are you doing ah?!
C: YEH is very busy so there's nothing happening now, but after the filming ends........
K: Because YEH is an actress now, we are not in the same path ....
MC: It's ok, KJK.....
C: Also, if their relationship is smooth, it'll be great if we can help to manage YEH (direct translation so it should mean to be her mgmt agent)
MC: YEH is the type which is very likeable right?C: Really not bad ~~K: Ya...really not bad~~
MC: yes.....didn't you tell her privately even once?K: I have ~
MC: ohhh~~~
K: right now we are getting along well and have become closer.
MC; What about looking from a man's perception?
K: hmm~ age gap is too wide.
MC: What's the age difference??
C: hehe ~ What wide age gap ???
K: hmm~ you know it....
MC: What's the age gap???
K: About 12 yrs old.....
C: Don't even know the actual age difference.... hahaha
K: More than what I thought.
C: Really so much older than her. hahhah
K: Ya that's why!
MC: Ai~ if it's truly love~~
MC: KJK, can't tell the age difference from the two of you
C: 8 yrs ~
MC: It's only 8 yrs la~
K: If what we said are to be taken account, what will happen ....
C: Just give it a go ..
MC: ya, so many people are watching...
K: Ok, then you will date Song Hye Gyo ...
C: haha~
MC: CTH is SHG???
C: Ah, not bad, not bad.
K: LOL
What's the age difference for both of you.
C: 5 yrs? NOt alot la.
MC: An appropriate age difference.
C: OK, then we will be together.
MC & KJK LOL
C: Ok, I"m KORI (??? don't know what is KORI)
Our KJK & YEH
CTY & SHG.
K: OK.
MC: Not bad!
KJK pretended not to know his and YEH's age gap...yet CTH ruined it for him again cause he is not even that close to YEH, yet he knows that KJK and YEH's age gap is only 8 years
Also CTH was pretending to be single as well because he made it seem like he was single, eventhough he has been with the same woman for 10 years (married her this year) so...deny, deny, deny

In November of 2005, KJK changed his mind

he finally admits that he'd like to date YEH during a LIVE interview
http://www.youtube.com/watch?v=u0UqLycTm-c so things must have gone well since then cause YEH was in his music video recently and he even gave her a ring and a scooter.
Also on January 1st of 2006 he says YEH is his ideal woman and the one that he would pick to date
http://www.youtube.com/watch?v=NT2kbBNDqloSang Sang Plus March 28, 2006 - Yoon Eun Hye makes a call to KJK:
http://www.youtube.com/watch?v=46dvkf-H1t8 The competitors were given the chance to call someone if they have a hard time answering the question given to them. Yoon Eun Hye called Kim Jong Kook but he wasn't able to pick up the phone.
KJK wont answer a stranger's call. Most probably YEH was using other ppl's handphone, so KJK did not answer it.....but noticed how she knows his number by heart
