Many people didn't know about this but, Yoon Eun Hye was (actually) a close dongsaeng to both Sparta and Ace. Even though she might look like an enemy to many of the couple's wishing fans, truth was, they were both very fond of her. She was their friend. Eun Hye even knew about the couple dating and she was happy for both of them.

It was true that she had been the closest woman to Sparta once, but that was just for the show. Off the screen and in real life, Eun Hye and Jong Kook were just oppa-dongsaeng and friends.

Today, Eun Hye had come to Running Man as a guest. The members all cheered and with the One Man who was just smiling shyly like how he always acted when they paired him with the female guests.

'Ah, no matter what. It is just a game. Really, really fun, huh? Just look how happy Kook Jong is.'

Jong Kook and Eun Hye started the game slowly and finally managed to get a remainder of 1.0 cm. Then, it was Ji Hyo and Kwang Soo's turn. The girin was already feeling uncomfortable but the nation MC comforted him saying that it was just a game (and one certain hyung would understand). Kwangsoo took a deep breath. 

This noona in front of the girin was not a stranger. They ha
