He shared the sorrowful story on the February 14 episode of '1 vs. 100' in response to the question asking about the negative side of having a small head. First Yoseob said, "Hats don't fit me. It's uncomfortable because I make it the smallest and it still doesn't fit."
He shared another negative of having a small head, saying, "Sometimes when I take pictures with my fans after a concert, they push me to the front even though they're my fans. One time it really hurt my feelings when a fan said, 'I'm not going to take pictures with Yoseob oppa'. They told me that I was the best but still wouldn't take pictures with me."
