Hajuseok and Kim Yeonjeong have revealed their 5-year secret relationship. On January 5, during the TV Chosun entertainment program 'Lovers of Joseon,' the couple discussed their romance and marriage. Hajuseok introduced himself as "a gentle man at home and a passionate man at the baseball field." Kim Yeonjeong said, "I am Kim Yeonjeong, the cheerleader who cheers hard and Hajuseok's wife."

Kim Yeonjeong disclosed that their relationship lasted for 5 years. She mentioned, "I thought we shouldn't be dating because he is a baseball player. I didn't want to break up, so I hoped no one would know we were dating, which is why we kept it a secret." However, she added, "I got caught by player Noh Si-hwan." Hajuseok explained, "Noh Si-hwan is quick-witted and figured it out by looking at the name in my phone." Kim Yeonjeong's name in Hajuseok's phone was saved as 'Ilchil,' which refers to her cheerleader number 17.

Regarding the changes after marriage, Hajuseok stated, "After we got married, the negative comments decreased even when I was struggling." Kim Yeonjeong laughed and said, "Fans send messages saying, 'Even if we don't scold you, you won't be able to eat at home,' and 'I'm dead to Yeonjeong unnie.'"

Kim Yeonjeong further explained the reason for their secret relationship. She said, "Actually, I thought we shouldn't be dating from the beginning. When I was first confessed to, I kept asking questions. If we broke up, I wanted it to be done without anyone knowing, so I thought it would be better if no one knew we were dating."

The news of Hajuseok's marriage became known last October when a commentator mentioned it during a game between the Eagles and the Landers. Kim Yeonjeong shared, "When it was suddenly announced in the middle of the season, I got worried and called, but the team said they had no concerns, while Hajuseok was excited to receive congratulations."

Hajuseok recalled a tough time due to poor baseball performance in the past. He mentioned, "My father said Yeonjeong's words helped me a lot and that I managed to gather my thoughts again." Hajuseok expressed gratitude, saying, "I was really thankful to Yeonjeong." Kim Yeonjeong added, "I thought Hajuseok wanted to quit baseball at that time. Given the situation back then, I honestly thought Hajuseok was a good person, bright, and hardworking, and I felt that if he quit now, it would end in a bad image. I thought it would be better for him to finish with a good image if he had the opportunity, even if he was to quit."

With Kim Yeonjeong's support, Hajuseok was able to regain his courage for baseball. The program's MCs praised, "He found a life partner well," "She is so beautiful," and "She made Hajuseok who he is now."

Hajuseok's parents initially thought Kim Yeonjeong would leave, but they evaluated everything positively. Kim Yeonjeong received a handwritten letter from Hajuseok's parents, expressing gratitude and affection. She said, "I feel like I married into a warm family."

The broadcast also revealed the scene of Hajuseok and Kim Yeonjeong's wedding. The wedding, attended by Eagles players and cheerleaders, was a celebration of their love. The story of Hajuseok and Kim Yeonjeong's secret relationship and marriage touched many hearts.
