After completing their filming for tvN's 'Youth Over Flowers', the idol group returned to Korea neatly dressed in suits, leading the viewers to wonder what actually went on.

During the January 9 broadcast of 'Youth Over Flowers', the behind story was unveiled featuring WINNER members traveling to West Austraila.

Na Young Suk PD handed them his personal card and said, "You will only have one chance to swipe the card."

With that, WINNER said, "Let's all dine in at a 5-star hotel," making Na PD nervous when they ended up going shopping instead.

Dressed in casual attire the singers stepped inside a clothing store and began trying out different outfits when they all decided to go classy wearing fancy suits on their flight back to their homeland.
