Nobody will ever wonder that the tough, hard, fierce Kim Jong Kook could be a sulking King behind the scene. And the only person who could make him like that is none other than his secret girlfriend, Song Ji-hyo. But Ji-hyo is also a sulking Queen herself. Which is why, the two just complement each other and is a perfect couple.

  In front of everyone, she was the star. She faked her smiles as long as they were happy. She's happy when her fans surrounded her and showed they were happy just by her appearance or attendance to certain event.

It's not easy being a secret couple. Especially when you have to work together. Especially when there's another girl competing with you. True he is your boyfriend. But for how long? Who could promise you that he'll never change? That's what have been playing in Ji-hyo's mind these days. And situation after situation didn't help curing her insecurities. Will Jong Kook manage to hold onto her heart till the end?  

It's always hard when you had a crush with someone especially whom you work with. At one point, it makes you happier every time you are going to work knowing that you will meet that special person. But on another point, it pains to deal with your own heart since you keep everything inside you alone. Will they confess their feelings one fine day? Or will they last as colleague, brother-sister forever? Enjoy the ride. 

They are supposed to attend the Running Man Fanmeet in Taiwan for 2018. But they couldn't fly together due to individual schedule. Will they still enjoy each other's companion within their limited times?

He kept everything inside him. Everyone knows Jong Kook is a very reserved person. He doesn't like to share his personal life especially when it's related to love and woman. But when one woman makes his feelings almost explode, he felt like he's going crazy since he could only talk to himself. Will he be able to to confess? How long can he keep it to himself?

While Jong Kook is busy with Turbo summer album and concert, Ji-hyo doesn't make it easier for him. Jong Kook kept feeling guilty towards his secret (not so secret) girlfriend since he has little time to spend with her. Thought Ji-hyo never complained, but some of her actions showed like she's rebelling. Or perhaps it was only Jong Kook who take things too serious due to his stress with his concert and comeback?

Ji-hyo was never happy when she needs to travel outside Korea alone, without her secret boyfriend or even other Running Man members. But this time, she's at her happiest moments when she travelled to Shanghai and received lots of surprises. When someone she never expected appeared at her door. When someone she loves dearly stood in front of her. She felt like dreaming. Yes she was happy. But can she handle two Kim's at once? 

It was a shocking day, not only for the Korean Entertainment Industry, but probably to all international Running Man fans.

They have been together for seven years now. The Running Man members are like a family now. But when Gary dropped the news that he's leaving the show, it seemed like the world almost collapse. And the person who was affected the most, was Ji-hyo since she has been working closely with Gary until they were called Monday Couple. But it's all on the surface. Deep down, there were other person who was hurt silently. Without anyone's knowing, someone else had knew anoth

Jong Kook has been missing her secret girlfriend, Ji-hyo for days now. So, knowing that they are going to have a Running Man shooting today, makes both of them happy. But, because of their feelings also, makes them even feel a bit sensitive towards each other, especially for Ji-hyo. Can Jong Kook handle his girlfriend?    

The love relationship between Ji-hyo and Jong Kook hasn't been good recently. To make it worst, Ji-hyo was offered to shoot for a show from China's production called We Are In Love which is like the Korean show We Got Married. Will Jong Kook be as understanding as he was towards Monday Couple when Ji-hyo shoot for this new show? Will their love remain strong as before?..............You'll never know..........    

It is Valentine's Day. Ji-hyo and Jong Kook usually celebrate it together although Jong Kook never understand why they need a certain day to celebrate their love. But since Ji-hyo likes it so much, Jong Kook always followed whatever his girlfriend wants. But this year, it's different. Ji-hyo already has an event to attend and it's not even in Korea, but in Hong Kong. Jong Kook didn't have a problem at first not having his girlfriend on Valentine's Day but as the da

Ji- hyo is always happy whenever she needs to go outside Korea with her secret boyfriend, Kim Jong Kook for work. But when she heard that this time Jong Kook wasn't able to join them in Shanghai, it saddened her. Jong Kook couldn't sit quietly especially when she didn't reply his text or answer his calls.  

Kim Jong Kook and Song Ji-hyo never know why it's hard for them to be partnered in the Running Man but the PD must have their own reasons and it never cause any problems for both of them if they weren't together because both of them will find their own way to try and be together without anyone notice. But, they need to be extra careful now that Kwang Soo started to be suspicious with them.

Ji-hyo is always happy whenever she needs to go outside Korea with her secret boyfriend, Kim Jong Kook for work. This time, they headed to Hong Kong for the Race Start 3. Many things and emotions involved between them. So let's see if they will survive hiding their relationship till the end.

Kim Jong Kook may have been acting for the first time in the drama "The Producer" which makes everyone excited and happy but the real happiness producer for him are his wife Song Ji-hyo and his daughter Kim Jin-kyung.
