[X X] (multiple multiple[1], Hangul: 멀티플 멀티플), sometimes stylized as [× ×], 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 Normal B and Limited A and B versions were released on February 26. At some point, the printing of some editions was halted.[citation needed]

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 two snippets served as previews of an ultimately cancelled ballad album, LOONA the Ballad.

Description[edit | edit source]

Album[edit | edit source]

While [+ +] portrayed a basic addition of each other, [X X] is an applied multiplication of each other.[2]

Music Video[edit | edit source]

Coincidence meets coincidence in LOOΠΔ to make each other’s fate.

HeeJin and HyunJin are real-life friends while HaSeul is like the mother of the team. YeoJin is the youngest sister of all. The team expanded its cells by family-like relationships. The only foreign member and an android ViVi gets introduced to become LOOΠΔ 1/3.

ODD EYE CIRCLE was born at the opposite end. With the story of three moons gathering to form a full circle, Kim Lip, JinSoul, and Choerry decide to stand at the frontlines to save the world, under their slogan ‘Girl Front’.

Born in Eden the utopian land, LOOΠΔ / yyxy chooses to embrace the forbidden and leaves to find their own selves. Yves, the leader of yyxy, had “faith” in being born again with the song ‘new’. Chuu keeps her “hopes" up with her yearning towards Yves. Go Won “loves” her unique self. Olivia Hye shows “anger” towards the taboos of Eden. When all of their emotions gather, a Neoanthropinae genes of yyxy manifests.

All of the units meet with YeoJin to add to the addition, resulting in their first EP [+ +] to announce the start of LOOΠΔ. At the ‘First full Moon of the LOOΠΔ new Year,’ LOOΠΔ starts their two-two-dimensional fusion with [X X].

Album[edit | edit source]

[+ +]가 서로가 더해졌을 때의 베이직한 결합을 담았다면, [X X]는 서로가 곱해졌을 때의 응용적인 결합을 담았다.[3]

Music Video[edit | edit source]

이달의 소녀는 우연과 우연이 만나 서로의 운명을 만든다.

희진과 현진은 자매 같은 동갑내기 실제 친구이고 하슬은 팀의 엄마 같은 존재이다. 그리고 여진은 막내 동생이다. 그렇게 서로는 가족 같은 관계성을 맺고 팀 세포를 늘려나갔다. 여기에 유일한 외국인 멤버이자 안드로이드 ViVi가 등장하며 이달의 소녀 1/3이 탄생했다.

ODD EYE CIRCLE은 이달의 소녀 1/3과 반대의 지점에서 탄생했다. 세 개의 달이 모여 하나의 원을 완성한다는 뜻으로 김립, 진솔, 최리는 ‘Girl Front’를 슬로건으로 소녀들이 앞장서서 세상을 구하기로 한다.

이달의 소녀 yyxy는 에덴이라는 이상향의 공간에서 탄생하지만 금기를 거부하고 자신만의 자아를 찾아 떠난다. yyxy의 리더 이브는 new라는 곡으로 새로운 나의 탄생을 믿으며(faith), 츄는 이브를 향한 동경을 소망(hope)한다. 고원은 자신만의 유일한 나를 사랑(love)하며, Olivia Hye는 에덴의 금기들에 분노(anger)한다. 그리고 각자의 감정들이 모일 때 하나의 yyxy라는 신인류 유전자가 발현된다.

모든 유닛과 여진이 만나 플러스 플러스한 첫 번째 미니 앨범 [+ +]로 이달의 소녀의 시작을 알렸고, First full Moon of the LOOΠΔ new Year(정월 대보름)에 이달의 소녀는 [X X]로 서로의 2차원적인 결합을 시작한다.
