“Hi High” (Hangul: 하이 하이) is the second and title track from the mini-album [+ +] by LOONA. It was released on August 20, 2018 as the official debut song of LOONA as a full group. The song was later included on the repackage album [X X] as the eleventh track.


The titled track ‘Hi High’ is a song in the genre of Hi Energy, emitting positive energy that the gathering of the twelve members create. The desire to play hard-to-get is portrayed in the lyrics through the characters of each member. HeeJin says, “I don’t want to pass my love on to you so easily,” while HyunJin says, “because I’m that pretty girl,” and Choerry says, “I’m not playing hard-to-get but boys will be boys, watch out, watch out,” telling what is on their minds candidly. The high BPM like a high-speed sprint along with melodies pouring down, and splendid track arrangements forces the listeners to hold their breath and focus on the music.

The official music video of ‘Hi High’, directed by the visual director Digipedi, narrates how LOOΠΔ 1/3 meets ODD EYE CIRCLE, and how these girls unite with yyxy to soar to the sky, with countless visual symbolism hidden in the scenes.[1]

타이틀 곡 ‘Hi High’는 하이에너지 장르의 곡으로 12명이 모였을 때의 기분 좋은 에너지를 발산한다. 사랑하지만 튕기고 싶은 감정을 멤버들만의 캐릭터를 통해 가사로 담았다. 희진은 “나의 사랑 쉽게 주고 싶지는 않아”라고 말하며 현진은 “난 예쁜 애니까”, 최리는 “밀당은 아냐 하지만 남잔 조심 조심” 하라며 소녀들의 감정 표현을 솔직하게 털어놓는다. 질주하듯 빠른 bpm에 쏟아내는 멜로디와 화려한 트랙 구성은 숨 쉴틈 없이 음악에 집중하게 만든다.

이달의 소녀의 비주얼 디렉터인 디지페디와 함께한 ‘Hi High’의 뮤직비디오는 이달의 소녀 1/3ODD EYE CIRCLE을 만나고, 그렇게 만난 소녀들이 yyxy와 결합하며 하늘 높이 도약하는 내러티브 속에 수 많은 상징들을 숨겨놓았다.
