Lee Joon plays the alumni card in a cheeky battle with Lee Seok Hoon

Lee Joon reveals school connection to Lee Seok Hoon's wife, sparking a 'pride battle'

A peculiar tension has erupted as actor Lee Joon was revealed to be an alumnus of singer Lee Seok Hoon's wife.

In a preview video for 'Songs That Sustained Today - Playlist 109,' which premieres on MBC on the 21st at 9 PM, Lee Joon boasted of his school-day fame, telling Lee Seok Hoon, "There is no way my sister-in-law doesn't know me." Lee Seok Hoon fired back by pulling out a photo of his wife from her school days. Upon seeing the photo, Lee Joon instantly shifted his attitude, yet continued the playful battle of pride by adding, "I was the face of the entire department."

DinDin, Lee Joon, and Lee Seok Hoon show 'three brothers' chemistry' across hierarchies

This program is a project that compiles 109 songs into a playlist, featuring 'sustenance songs' that helped individuals get through difficult moments along with the stories behind them.

The MC lineup is also drawing attention. DinDin, who earned the image of a 'celebrity disease cure' for Lee Joon through the Mega MGC Coffee episode of the channel Workman last August, has joined the cast. From their very first meeting, DinDin made the set burst into laughter by referring to Lee Seok Hoon as "Sleepy with glasses," citing something he heard from Sleepy. The eldest, Lee Seok Hoon, cheekily responded, "I feel quite bad about that."

First guest is actor Park Shin-yang: "Crawling on hot asphalt..."

Actor Park Shin-yang has been selected as the first guest. The appearance of Park Shin-yang, who rarely appears on variety shows, left the production team and MCs, including Lee Seok Hoon, Lee Joon, and DinDin, unable to hide their surprise.

In the pre-released video, Park Shin-yang piqued viewers' curiosity by starting his story with the phrase, "I was crawling on hot asphalt..." The cast is set to begin their musical journey through the 'sustenance song' Park Shin-yang will share and the sincere story hidden behind it.

MBC's 'Songs That Sustained Today - Playlist 109' premieres on the 21st at 9 PM.
