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
