[X X] (multiple multiple) is the repackage album of LOONA's debut mini-album [+ +].

It was digitally released on February 19, 2019 along with its title track's music video, "Butterfly". However, the physical album release was delayed. Normal version A became available on February 21, while the rest were to be released on February 26. At some point, the printing of some of the editions was halted.

The limited editions of the album include 2 hidden tracks: "Stay With Me Babe" on the Limited A version and "Daydream" on the Limited B version. Those 2 snippets served as previews of a future ballad album, "LOONA the Ballad".


While [+ +] portrayed a basic addition of each other, [X X] is an applied multiplication of each other.[1]
