[Romanized:]
Dooshite nemure-nai no?
Dooshite yoru wa owaru no?
Ira-nai nani mo, ashita sae mo,
kimi ga i-nai mirai.
Dooshite waratteta no?
Dooshite samishikatta noni?
Dare mo shira-nai, hontoo wa tada
soba ni ite hoshikatta.
Zetsuboo sae mo hikari ni naru.
Yama-nai ame ga furi tsuzuite mo.
Zetsuboo sae mo hikari ni naru.
Kanashii ame ga niji o kakeru yo,
doko made mo.
Nidoto ae-nai kedo
wasure-naide itai yo.
Yume ga tsuzuku nara
same-nai de.
Dooshite waratteta no?
Dooshite samishikatta noni?
Dare mo shira-nai, hontoo wa tada
ai-tai. Sore dake datta.
Zetsuboo sae mo hikari ni naru.
Yama-nai ame ga furi-tsuzuite mo.
Zetsuboo sae mo hikari ni naru.
Kanashii ame ga niji o kakeru yo,
ima mo.
Yama-nai ame ga kokoro mitasu yo,
itsu made mo.
