Rōmaji
Kono ryoute ni kakaete iru mono toki no shizuku

Sotto nigirishimete wasureta kioku nakushita kotoba

Hitotsu hitotsu omoidaseba

Subete wakatteita kigashite ita no ni

Iroaseta kotoba wa boku no sugu soba ni oite atta

Kotae no denai yoru to

Hitokira no nukumori to

Haruka kanata no akogare to

Tada sore dake wo kurikaeshi boku wa ikite iru

Kono ryoute ni kakaete iru mono toki no shizuku

Sotto nigirishimete wasureta kioku nakushita kotoba

Anata ga omou koto wo sameru koto nakutemo to ni tsukamitai no ni

"Hito" dearu bokutachi wa sono kimochi wo wakachi aenai mama

Kotoba ga hanatsu imi wo

Tatoe no nai omoi wo

Kotaeru koto no nai kanjou wo

Mitsumeaeba tsutawaru koto ga dekitara ii no ni na

Kono ryoute ni kakaete iru mono toki no shizuku

Sotto nigirishimete wasureta kioku nakushita kotoba

Kono omoi wa mune ni shimatte okou

"Nakushite shimatta…"
