Niji akari sunda sora ni hikaru
Ameagari nanairo ni
Hito wa sukoshi zurushite mo ii
Mizukara ga aruki dasu michi wo terashite
Isogu jitensha no beru no oto
Futari dake no aizu "ohayou" dane
Hachigatsu no owari ooki na kibou mune ni
Tabidatsu kimi ga tottemo akogare datta
Bokura juu-nen goshi no tegami kaki
Futari taimukapuseru ni gan kake
Otagai furi kitta te ni wa
Shourai wo egakou
Kimi no koraeta namida no bun
Boku ga ima oogoe de naku kara...
Saki ni se wo mukete aruki dashite kudasai
Hakusen hiita sutaatorain
Wasure naide kimi ga tobi tatte yuku soba de
Nagareru namida ga ima koko ni aru koto
Hiruyasumi okujou sora miage
Yurugi nai "ketsui" kiita yo ne
San-ji juu-go-fun tsukue no rakugaki
Keshite seki wo tatsu sorosoro shuppatsu no jikan
Bokura juu-nen gosh mo kouyatte
Ireru you ni to itsumono egao de
Otagai yubikitta te ni wa
Mirai he kazasou
Kimi no kuchiguse "itsuka wa... "
Sono tsuduki ni boku mo make nai you ni
Kitto hane hiroge tobi tatte yukitai
Hakusen hiita sutaatorain
Shingakki kaerimichi
Yakimashita shashin
Hohoemu kimi no egao
Yuuki ni shite shanto mune harou
Bokura juu-nen goshi no tegami kaki
Futari taimukapuseru ni gan kake
Otagai furi kitta te ni wa
Shourai wo egakou
Kimi no koraeta namida no bun
Boku ga ima oogoe de naku kara...
Saki ni se wo mukete aruki dashite kudasai
Hakusen hiita sutaatorain
Kokoro kara kanshasuru yo saiai no hito
Saikou no raibaru
Kimi no sonzai kimi no egao ga
Boku ni totte taisetsu na taisetsu na takaramono
Tooku kara inotte iru
Sorezore ni susumu asu he no chizu
Yakusoku zutto oboete iru
Itsuka koko de mata aeru koto wo
