On February 12, Sechskies appeared as guests on the Lunar New Year special episode of 'Yoo Hee Yeol's Sketchbook'!

Last week, Sechskies greeted fans with a new comeback track written, composed, and produced by Yoo Hee Yeol. The project was all a part of a series of games and prizes which began during Sechskies's 'Three Meals for Four', a spin-off series from the 'New Journey To The West' universe. 

On this episode of 'Sketchbook', Sechskies performed their comeback ballad track "Don't Look Back" for the first time ever live! In addition, the group gave a cheerful rendition of their biggest hit "Couple", as well as a piano rendition of "Pongsaeng Pomsa" with Yoo Hee Yeol on the piano!

During their interview segment, Sechskies gave their thoughts on ranking #1 on music charts immediately after the release of "Don't Look Back". Thanking their fans as well as all who were involved in the production of "Don't Look Back", Sechskies's Kim Jae Duk said, "We actually each made a promise for if we ranked 1st place. One was that whenever Hee Yeol-hyung called us, we would act as backup dancers for whatever he needed us for." 

Here, Lee Jae Jin added on, "For this comeback, hyung wrote a song for us. So next time, I thought that it would be nice if we wrote a song for hyung." Eun Ji Won agreed and chimed in with, "We will give you a good dance song." The other Sechskies members also promised that they would act as backup dancers for Yoo Hee Yeol's second debut as a solo dance artist.

Hearing all of this, Yoo Hee Yeol responded, "I am very scared. Can you guys stop saying whatever you want on broadcast?"

But the Sechskies members continued to talk about Yoo Hee Yeol's debut as a solo dance artist with excitement. Finally, Yoo Hee Yeol gave and said, "You know what, I will seriously consider this."
