ZE:A's Siwan reveals his impressive resume on '1 vs 100'

Siwan shared, "During my student days, I didn't have the courage to step out of line. I've placed first in my class and at my school. During middle and high school, I was also the class vice president."

He continued to explain, "The reason I studied hard in high school was because I thought I would be able to get away from exhausting studies when I got to college. However, I had to study even harder in college. I happened to participate in a song festival and got in touch with my current agency to debut as a singer."

Siwan made the '1 vs 100' audience laugh by confessing, "I couldn't sleep. I was surprised when I heard that Kwanghee came on the show and went all the way to the 8th level. I couldn't sleep because I was worried that I would do worse than Kwanghee."

Tune in to the August 13th broadcast of '1 vs 100' to find out if Siwan was able to surpass Kwanghee's record.
