A family feud breaks out between 'adopted son' Son Tae-jin, 'adopted daughter' Jeon Yu Jin, and 'biological son' Lee Seung-hyun as they compete for the love of trot legend Seol Woon-do. The 745th episode of KBS 2TV's "Immortal Songs," airing on February 21, is a special edition titled "Immortal Songs - Artist Seol Woon-do," revisiting Seol Woon-do's classic hits. This broadcast features talented junior artists from various genres aiming to claim the next legend title with their performances.

The lineup includes Son Tae-jin, Jadu, Kim Su-chan, Lee Seung-hyun, LUN8, Cheon Rok Dam, D82, Jeon Yu Jin, Kim So-hyang & Yoon Hyung-ryul (musical team), and Park Seo-jin. They will reinterpret Seol Woon-do's masterpieces, showcasing their unique charms. Notably, an unexpected family quarrel unfolds in the talk waiting room, bringing laughter.

Son Tae-jin, who received his debut song from Seol Woon-do, is known as "Seol Woon-do's adopted son." However, Lee Seung-hyun expresses resentment toward Son Tae-jin, revealing tension between the two. The "turtle stone" that Son Tae-jin personally brought serves as the catalyst for this conflict. Son Tae-jin proudly states, "Only two people have received a stone from the teacher: me and Lim Young Woong." In response, Lee Seung-hyun adds humor by saying, "That was really at Dad's villa, and I'm not even allowed to touch it."

Jeon Yu Jin also joins the family feud. She mentions, "Teacher Seol Woon-do is like a father in the trot world who has witnessed my entire growth as a singer," stepping up to compete with Son Tae-jin. Regarding the "turtle stone" Son Tae-jin brought, Jeon Yu Jin declares, "I have never received a stone from Teacher Seol Woon-do. My goal today is to receive one." This sparks a "dad's love battle" among the biological son, adopted son, and adopted daughter.

In this episode, Son Tae-jin and Jeon Yu Jin shed their past roles as the "Trot Trendy Jinjin Siblings" and form a fierce rivalry. Jeon Yu Jin chose "Samba Woman," while Son Tae-jin selected "Love's Twist." Jeon Yu Jin said, "I've never shown a performance on 'Immortal Songs' before. Today, I focused on the performance with a diva concept." Son Tae-jin fired back, "I also prepared a performance. I'll beat Yujin with my performance and make it a year's worth of teasing material."

Jeon Yu Jin fueled her competitive spirit, saying, "Losing to Son Tae-jin oppa in performance would really hurt my pride." This prideful showdown between the "Jinjin siblings" is highly anticipated.

"Immortal Songs - Artist Seol Woon-do" will continue with Part 2 airing on the 28th, following the Part 1 broadcast on the 21st. Airing every Saturday at 6:05 PM, "Immortal Songs" is beloved for creating legendary videos that viewers want to watch again.
