写下「逆袭神话」的女子组合H1-KEY为《特务家族》发声，担任OST的第一棒。 《Danger》以管弦乐为基础，将丰富的声音和现代流行音乐适当混合，展现高完成度的音乐。虽然气氛凄凉危险，但是以机智的感觉为特征，中毒性的副歌反复句让歌曲的魅力倍增。 《特务家族》 讲述伪装成平凡上班族的国情院黑色要员丈夫权道勋（张赫 饰）与梦想完美家庭、甜美的妻子姜宥拉（张娜拉 饰）之间惊险的死守家庭谍报喜剧。首支OST H1-KEY的《Danger》预计会进一步提高了观众们的共鸣和投入度。 [Credits] Lyrics by 리선, 산해, ABOUT Composed by ABOUT, KIME, HEMO Arranged by ABOUT, KIME, HEMO Vocal Directed by 김연서 Background Vocals by 김연서 Recorded by 김희재 @ CS MUSIC& Studios Engineered for Mix by 박남준 @ GLAB Studios Mixed by 신봉원 @ GLAB Studios Mastered by 도정회, 박준 @ SoundMAX OST Producer 김정하, 이다임, 윤민아
