TVXQ members Xiah Junsu and Max Changmin participated directly in the making of the album, penning the lyrics for "노을.. 바라보다 (Picture of You)" and "Love in the Ice", respectively.

"[6] The choreography of "주문-Mirotic," the title track of the album, was done in a collaboration between Korean choreographers and Kenny Wormald, who had also worked with pop stars Justin Timberlake, Chris Brown and Christina Aguilera.

"Mirotic" is a newly coined term, created by member Hero Jaejoong, that combines the Korean miro (미로), meaning "maze", and the English suffix "-tic".

Hwang Seon-eop, an editor of South Korean magazine IZM, rated the album 3.5 out of 5 stars, praising the record's production and the group members' performance.

[8] In November 2008, the Korean Commission of Youth Protection ruled that the lyrics of "Mirotic" were provocative and overly sexual.

As a result, the album was labeled with stickers indicating that it was unsuitable for people under 19 years old and any performances of the song would have to be broadcast after 10pm.

[14] The following month, the Commission of Youth Protection announced they would appeal the ruling to a high court after having an emergency meeting and deeming that the phrase, "I got you under my skin", was inappropriate for minors.
