It's really fascinating how you manage Dun's stamina.

Dawn was on "I Live Alone" yesterday, and it was really fun. It was fascinating to see him getting sunlight because of his chronic adrenal syndrome.

I was doing the Dawn Challenge to follow Kim Moo-yeol's workout and finish it in 30 minutes, and it looked really tough.

It was totally hilarious when I was taking a walk after my workout and Kim Dae-ho and Kian84 kept teasing me, saying all I could see was my chest muscles.
