zutto zutto sono egao wo
tayasazu ni ite hoshii
kitto sore ga chikara ni naru
asu wo mamoru tame no
That's why to be

bokura wa naze umareta no ka?
bokura wa naze ai suru no ka?
nantonaku ne,
chikagoro futo kangaetari suru

shiawase wa egao no kazu dake aru n' da...
kimi wo mite iru to kokoro kara sou omou

kageri no nai sono egao ga
boku ni tsutaete kureru
meguru toki wo tsunagu tame ni
umarete kita n' da to
That's why to be

wakeau koto wasurenaide
yurusu koto wo osorenaide
tayasui koto ja nai keredo
kitto dekiru hazu

kanashimi ga toki ni hikari ubau keredo
kesshite nigenaide koete yukeru kara

sou sa, hito no kokoro nante
omou hodo yowakunai
sonna fuu ni kurikaeshite
tsuyoku umarekawaru
That's why to be

dare no te mo ikiru kibou wa kesenai yo
shinjiru koto kara subete hajimaru sa

hitotsu hitotsu bokura no yume
yasashisa de atsumetara
eien ni mo todokisou na
sonna ki ga suru kara
That's why to be

kageri no nai sono egao ga
boku ni tsutaete kureru
meguru toki wo tsunagu tame ni
umarete kita n' da to
That's why to be
