Haseul's "Let Me In", by the production team OREO led by Iggy who completed GFriend's school-themed trilogy, is a blockbuster track that starts as a calm winter ballad before strings roar over like a blizzard.
Digipedi and BlockBerryCreative filmed in faraway Iceland for the music video, and fulfilled the music's scale through the scenery of Iceland.
걸그룹 '여자친구'의 학교 3부작을 완성한 이기의 프로듀싱팀 'OREO'가 만든 '하슬'의 "소년, 소녀"는 차분한 겨울 발라드로 시작해 눈보라처럼 스트링이 휘몰아치는 블록버스터 트랙이다.
뮤직비디오를 위해 멀리 아이슬란드까지 디지페디와 블록베리크리에이티브는 촬영을 진행했으며 음악의 스케일을 아이슬란드의 영상미로 완성했다.
The MV was filmed at the Sólheimasandur plane wreck in Iceland. The “XIIX” teaser with Go Won was shot in the same location.
The phrase “Je ne saurais pas recommencer” (I will not know to restart) is sometimes transcribed by fans as “Tu ne saura pas où commencer” (You will not know where to start). As there are no official lyrics for the line in question, all existing transcriptions of this line are technically speculation, and the version provided in this article is merely a best guess after careful listening.
The voice that says “Je ne saurais pas recommencer” is sometimes thought to be Go Won; however, Go Won had not joined BlockBerryCreative at the time “Let Me In” was recorded, so her voice being present on the track is almost impossible.
