In "The Seasons - Lee Young-ji's Rainbow," Lee Young-ji shed tears that she had held back at the appearance of producer Na Young-seok.

On the broadcast of KBS2TV's "The Seasons - Lee Young-ji's Rainbow" on the 21st, producer Na Young-seok made a surprise appearance.

On this final broadcast, a surprise video message for Lee Young-ji was revealed. The members of IVE expressed to Lee Young-ji, "You're amazing despite being busy, you've worked hard for so long, you're the best MC," and Mimi and Lee Eun-ji also said, "Young-ji, you've worked hard. Even though you're younger, I respected you. You've done well, and I love you. Let's be happy."

Also appearing in the video were Park Jae-beom, a senior MC from "The Seasons," and Jannabi. Other celebrities including Bukseoksun, Mark, Kim Yeon-ja, and Ko Kyung-pyo conveyed their greetings, saying, "You've worked hard all this time." In particular, producer Na Young-seok in the video also said, "Congratulations" and noted, "When you worked with me, you were a troublesome girl, but I felt proud watching you brilliantly lead the program as a musician and MC."

Upon seeing the video message, Lee Young-ji was surprised, saying, "We don’t usually talk about these things with each other."

Na Young-seok noted, "I wanted to greet everyone on stage, but I was scared they would make me sing, so I couldn’t go on," and added, "Let's talk about the next thing in the Joyful Room. You've worked hard, and congratulations."

After the video, Lee Young-ji was touched, saying, "I think that friend must have a lot of friends. I truly appreciate it."

At that moment, producer Na Young-seok made a surprise appearance on stage. Lee Young-ji was taken aback by his unexpected arrival, and Na Young-seok greeted her with, "You were very surprised, right?" He added, "Our Young-ji is on her last day. She is my daughter born through entertainment, and I came out to congratulate her one last time," to which Lee Young-ji remarked, "I’m really touched."

In particular, producer Na Young-seok, a former KBS entertainment producer, is visiting his home station for the first time in 13 years, having directed numerous hit shows including "1 Night and 2 Days," "Grandpa Over Flowers," and "Earth Arcade." Recently, he is gaining popularity by being the first entertainment producer to hold a fan meeting. Na Young-seok, known as Lee Young-ji's entertainment father, has shown great chemistry with her while working on "Earth Arcade."

Na Young-seok said, "Thanks to you, I came to KBS after 13 years," and added, "I came out because I won’t be asked to dance or sing." However, Lee Young-ji immediately encouraged him to "sing," and contrary to his prior agreement with the production team to participate as a special MC without dancing or singing, Na Young-seok showcased the 'First Meeting Challenge' dance from TWS (Tourus) at the persistent requests of Lee Young-ji and the audience, bringing great laughter to everyone.

As the song "First Meetings Don't Go as Planned" played and Na Young-seok succeeded in dancing, Lee Young-ji said, "I just want to say one thing: I didn't cry watching the video message, but seeing the dance made me feel like I could cry honestly. Thank you so much for coming, I'm touched," though Na Young-seok, who did not expect to be on the broadcast, laughed and said, "I know where the editing room is, the producers and the chief producer here are all my juniors," prompting Lee Young-ji to respond, "You're threatening me, so I’ll suddenly become someone who cries."

Na Young-seok stated, "Today, I represent the audience. You all worked hard on the last recording," and noted, "I don’t usually watch everything; I just see it through the algorithm. I always watch to see what our Young-ji is wearing; she looks so beautiful," showing a fatherly attitude. Na Young-seok also remarked, "Every time I see you here, in the Joyful Room, you were always in awkward towels with your face all messy, but here it’s like night and day, it’s magnificent, beautiful attire, and there's a lot of fun in watching your face."
