In the fourth episode of MBN's variety program 'The Men Within,' a total of 32 participants, including the TOP7 members (Seongri, Haru, Jang Hanbyeol, Hwang Yoonseong, Jeong Yeonho, Lee Changmin, and Lee Rune) and their families, will compete in a 'Family Chongbaek Battle,' showcasing diverse performances and personal stories.

In this broadcast, Seongri's older brother appears first and surprises the studio. Boasting a voice nearly identical to Seongri's, the older brother reveals himself to be a passionate fan of 2AM, expressing his fandom toward Jo Kwon, who visited the studio, and TOP7 member Lee Changmin. This prompts a joking remark: "Isn't Seongri's brother cheering for Lee Changmin more than his own sibling?" filling the set with a warm and friendly atmosphere.

Next, Seongri and Lee Rune face off in a 'Battle for First Place.' Seongri recreates Lee Rune's signature pelvic rotation dance and red socks for his stage, playfully provoking his opponent by saying, "I deliberately did Rune hyung's mirror mode." In contrast, Lee Rune delivers an heartfelt performance dedicated to his youngest sister. After the stage, Lee Rune's sister opens up about her feelings: "When he said he wanted to become a singer at a late age, he came up from Mokpo with no money, carrying onions and hauling bottled water. I'm sorry our family couldn't help him more."

The highly anticipated first head-to-head clash between Haru and Jang Hanbyeol also draws excitement. Jang Hanbyeol delivers a finals-caliber performance with his overwhelming 'three-step high notes,' leaving MC Jang Minho in awe as he exclaims, "You really put your life on the line." With family members gathered in one place, Haru confesses, "Seeing everyone's family together like this makes me think of my mom," and sings a sorrowful song in front of his maternal grandmother. After the performance, his grandmother gives Haru a tight hug, saying, "Thank you, our baby." Seongri and Jo Kwon were also deeply moved by Haru's stage and shed tears.

Elsewhere during his battle with Lee Rune, Seongri performs an acrostic poem filled with dad jokes, turning the set into a sea of laughter. Various episodes from the families and their passionate performances continue to unfold.

Episode 4 of 'The Men Within' airs on the 5th at 9:40 PM.
