[Chorus: Huening Kai, Soobin]
Naze boku wa anata no koto o
Ai shite shimatta nodarou
Aisa reru koto bakari ki ni shite ita
Hitori no yoru

[Verse: Beomgyu, Yeonjun]
Tōku de mi teta dake no hibi
Anata ga mabushikatta
Marude eiga no wanshīn no yō
Boku wa wakiyaku no mama

[Pre-Chorus: Taehyun, Soobin]
Dōsenara kono mama no futaride ireba
Nanihitotsu kizutsuku koto nado (nakattanoni)
Aisaretai soredake no atarashī kimochi ga
Mebaeta toki ni sekai wa kawatta

[Chorus: Huening Kai, Yeonjun]
Naze boku wa anata no koto o
Ai shite shimatta nodarou
Aisa renai koto nante wakatte ita
Hitori no yoru

[Bridge: Taehyun, Huening Kai, Yeonjun, Soobin]
Warau kao mo naku kao mo
Boku janai dareka no mae de
Kata ni yorikakaru anata no koto o
Amegafuru samui yoru mo
Kūki ga tsumetai asa mo
Boku ga soba de nante
[Interlude: Beomgyu, Yeonjun, Taehyun]
Nazedarou ka hitomi tojireba
Anata no koto bakari
Omoidasu ano mujaki ni warau kao

[Chorus: Huening Kai, Taehyun]
Naze boku wa anata no koto o
Ai shite shimatta nodarou
Aisaretai sō omoinagara nemuru
Hitori no yoru

[Outro: Beomgyu, Taehyun]
Hitori no yoru
Ah, ah, ah
Ah, ah
