Letra da Música Sekirara No Nikki de Serial Number

Maru-gatsu datsu-nichi kyou wa kimi no umareta hi da ne

Soshite... bokura no mirai ga marude
[SHABON]dama no you ni hajikete shimatta hi demo aru ne...

Arekara daibu tatta kedo kimi wa doushite iru no kana?

Saikin yoku omou
hayaku koishinakuchatte
kako ni sugari tsuitetemo [DAME] datte
wakatte wa iru n'da
sorosoro jibun no kimochi ni [KERI] wo tsuke you

Sasuga ni mada kimi hodo suki ni nareru hito wa arawarete nai kedo...
deai wa itsuka kitto aru!
sou yatte omotte nai to itsu ni natte mo kibun ga ochikonda mama da yo

Mae no nikki wo yomikaeshite miru to [NEGATIBU] na kotoba shika kaite nai ya
korette sukoshi wa mae yori [POSHITIBU] ni natta tte koto na no kana

Sasuga ni mada kimi hodo suki ni nareru hito wa arawarete nai kedo...
deai wa itsuka kitto aru!
souyatte omoi nagara korekara wa hibi ikiteiku koto ni shiyou

Mou futari kiri de wa sugosenai darou kedo maitoshi kyou to iu hi wo tooku kara iwau yo
sasuga ni chokusetsu ai ni nante ikanai kara
kore kurai wa sasete kure yo na

Rainen mo kou yatte koko ni kaki tsuzurou
kimi ni todokimasu you ni...
kokoro kara happy birthday to you
