SECRET's Ji Eun�also won her first round, but sadly lost to 'Jingle Jingle Lark' during her second round. All the same, she awed with her incredibly sweet voice.

The winner of the night was 'Jingle Jingle Skylark', who won over BTOB's Sungjae with her version of Ailee's 'I'll Show You'. She also beat the previous champion 'Used Two Buckets of Gold Lacquer', so we finally got to see who the champion of the first two rounds were!

'Gold Laquer' performed "Don't Think You're Alone", and while she sadly lost to 'Lark', viewers finally got to see who the she was. Sadly, things were a little anti-climatic she turned out to be exactly who everyone had already guessed she was - f(x)'s Luna. All the same, she expressed her gratitude at being able to sing without any stereotypes hanging off of her, and ended up in tears.

Congratulations to both Luna and the mysterious 'Lark'! Hopefully Luna'll get more and more chances to showcase her amazing voice!
