[#] (Hash,[1][2][3] Hangul: 해시; also known as Sharp,[4] Hangul: 샵) is a mini-album from South Korean girl group LOOΠΔ. It was released on February 5, 2020, including lead single “365” and title track “So What”.

It was announced[5] on January 7, 2020 via Fancafe that HaSeul would not be participating in promotions for this album due to mental health concerns.

The members’ individual teasers were released at 12am (KST) and 2:05pm (KST), the latter being in reference to the date the album was released, February 5.



If [+ +] was about the basic combination of adding each other, [X X] was about the applied combination of multiplying each other.

Just like how # has little meaning when used by itself, but manifests in special functions or great achievement when used alongside words and characters, [#] is about how we can realize results from multi-use combinations when we are together.[6]

Music VideoEdit

Fate collides fate in LOOΠΔ to make coincidence.

12th member, Olivia Hye and the 1st member HeeJin meets in fate and made LOOΠΔ as a whole world.

[#] does not mean much when it is used alone, but it means that when # is used in combination with words or letters, they realize the result of a multi-use combination when they are together, just as they perform a special function or great ability.

Through this album, LOOΠΔ want people to break out of the box, boundaries and prejudices, showing them to not to be afraid to challenge yourself. It is possible to make different waves more than you can imagine if you challenge yourself with your passion(BURN), and go forward.

On “THE BACK OF THE MOON”, which no one knows about, instead of a moon that does not shine on its own and always shows the same side, LOOΠΔ serves as a fuse in the heart of the whole LOOΠΔs around the world.

Through this album, LOOΠΔ is about to show the whole different confident, challenging LOOΠΔ, not the same LOOΠΔ people all know.[7]


[+ +]가 서로가 더해졌을 때의 베이직한 결합을 담았다면 [X X]은 서로가 곱해졌을 때의 응용적인 결합을 담았다.

[#]는 단독으로 쓰일 때 크게 의미가 없으나 #가 단어나 문자와 함께 쓰일때 특별한 기능 또는 대단한 능력을 발휘하는 것처럼 서로가 함께일 때 멀티 유즈한 결합의 결과를 실현한다는 의미를 담고 있다.[8]

Music VideoEdit

이달의 소녀는 운명과 운명을 충돌시켜 우연을 만든다.

열두 번째 멤버 Olivia Hye와 첫 번째 멤버 희진이 숙명처럼 만나 이달의 소녀라는 하나의 세계를 완성시켰다.

[#]는 단독으로 쓰일 때 크게 의미가 없으나 #가 단어나 문자와 함께 쓰일 때 특별한 기능 또는 대단한 능력을 발휘하는 것처럼 서로가 함께일 때 멀티 유즈한 결합의 결과를 만들어 낸다는 의미를 담고 있다.

이달의 소녀는 이번 앨범을 통해 기존의 틀에서 벗어나 경계와 편견을 넘어 세상의 모든 소녀들에게 도전하는 것을 두려워하지 말고, 자리에서 일어나 뜨거운 열정(BURN)으로 세상에 도전하고 전진한다면 상상 이상의 변화의 물결을 만들어 낼 수 있다는 이야기를 전한다.

스스로 빛을 내지 않고 언제나 같은 면을 보여주는 달이 아닌 “THE BACK OF THE MOON” 아무도 모르는 ‘달의 뒷면’에서 이달의 소녀는 전 세계 이달의 소녀의 마음에 불을 붙이는 도화선 역할을 한다.

이달의 소녀는 이번 앨범을 통해 기존의 이달의 소녀가 보여준 것과는 완전히 다른, 당당하고 도전적인 모습을 보여줄 예정이다.
