Kang Seung Yoon revealed a rather surprising and peculiar hygiene fact about himself.
On December 13, 'WINNER TV' showed the WINNER members getting ready to pack up for Japan. As you may remember, the boys opened up for Big Bang's 6-dome tour around the country.
On the episode, Song Min Ho said, "Can I get a bag for my underwear? I don't know if I should bring 4 or 5."
To this, Kang Seung Yoon replied, "I change my underwear every 2 days", surprising all of his group mates. He quickly explained, "I usually don't sweat."
