Comedian Mun Se-yoon challenged the Music Bank stair photo.

On the 21st, Mun Se-yoon posted a photo on his personal account with the caption, "Music Bank... a dangerous game... #MusicBank #DangerousGame #TeachMeHowToExit."

The released photo shows Mun Se-yoon attempting the Music Bank stair shot. The Music Bank stair is where idol singers enter inside the stair railing to showcase their thin waists or bodies. Mun Se-yoon joined in.

Mun Se-yoon appeared to have a painful expression as if his upper body was stuck. Upon seeing this, actor Lee Sang-yeob asked, "Hyung, are you still here?" Hong Hyun-hee said, "Are you going in or coming out?" Kang Jae-joon reacted, "Ah, you cut it and then welded it," which drew laughter.

Meanwhile, Mun Se-yoon is actively participating in shows such as tvN "Amazing Saturday" and KBS2 "2 Days & 1 Night." Recently, Mun Se-yoon released a duet track titled "Teach Me" with Han Hae and transformed into an emotional ballad artist, garnering attention.
