Red Velvet's Seulgi and Wendy shared the story behind their debut.

On the December 12 airing of JTBC's 'Give Me a Meal,' Seulgi revealed, "I auditioned in 6th grade and started training in middle school." She added, "I really enjoyed singing and dancing since I was little."

MC Kang Ho Dong also asked how Wendy became a singer. She answered, "I'm the type that gets nervous a lot but I didn't get nervous at all because I was with my friend. I sang a song that I like. I made it after singing Kim Gun Mo's 'Moon of Seoul.'"
