X1 members competed fiercely for "Move" dance by Tae-min.

Upon its debut at JTBC's "Idol Room," which airs on Sept. 10, "X1," a rookie group that continues its No. 1 march on various music shows, will appear.

In the recording of "Idol Room," member Kim Woo-suk showed off his frank and confident charm by saying, "I'm doing one sexy thing." After hearing Kim Woo-suk's remarks, the members went to check, refuting Kim's claim, saying, "I'm also confident if I'm sexy." They each appealed to their charms, including "power sexy" and "cute sexy." Kim Yo-han, who is now the No. 1 man in the decadence, immediately showed unusual eyes and poses, gaining explosive acclaim.

To pick the sexiest member, the "Move King" contest, which links girl group "Habana Queen's Contest," was held for the first time in "Idol Room." The "Move King Contest" is a segment where people dance to SHINee Taemin's hit song "Move" and show off their own charms. Rumor has it that the members put themselves in the rhythm of "Move" and passionately vented their sexiness.

The site of X1's first "Move King Contest," which cannot be seen anywhere else, can be found at JTBC's "Idol Room," which will air at 6:30 p.m. on Sept. 10.
