Kon'ya watashi shin'de shimaou kana
Odokashitatte mou kaeranu kokoro
Kore ijou anata wo tsukaresasecha
Omoidashitaku mo nai koi ni naru

Hitamukina shisen' ya sono SHATSU no nioi ga
Watashi wo surinukete yagate usurete yuku

"I know" "I know"
Watashi wa ima nara heiki yo
"I know" "I know"
Anata ga saigo ni nayamanu you ni
Futte ageru

Motto shiorashii ko ga niau noni
Dou shite watashi wo suki ni natta no
Kimagure ja nai wa to shin'jita kara
Don'na doryoku demo tanoshikatta wa

SHIIZUN' no PEEJI ga sakasama ni mekurete
Ichiban' waratteru SHOTTO de tomatteru

"I know" "I know"
Ano hi no futari wa kienai
"I know" "I know"
Watashi ga jiyuu wo nozon'da fuu ni
Futte ageru

"I know" "I know"
Watashi wa ima nara heiki yo
"I know" "I know"
Anata ga saigo ni nayamanu you ni
Futte ageru
