Happii shinsesaiza(happy synthesizer) kimi no mune no oku made
Todoku youna merodei(melody) kanaderu yo
Hakanaku chitta awai kataomoi
Waraibanashi dane ima tonareba
Miru mono subete kagayaite mieta
Ano hibi ga kirei ni waratteruyo
Gaman suru koto dake oboenakya ikenaino?
"otona ni natte choudaine?" naranakute iiyo
Shiranai koto bakari shiranai nante ienakute
"taihen oniai de" usotsuite gomen ne
Happii shinsesaiza(happy synthesizer) kimi no mune no oku made
Todoku youna merodei(melody) kanaderu yo
Tsumaranai "tatemae" ya ya na koto zenbu
Keshite ageru kara kono oto de
Nanno torie mo nai boku ni tada hitotsu
Sukoshi dakedo dekiru koto
Kokoro odoraseru kazaranai kotoba
Denshion de tsutaeru yo
Suki ni naru koto rikutsu nanka janakute
"kojitsuke" nante iranainjanai?
Jidai no seito akirametara soko made
Fumidasanakucha nani mo hajimaranai
"gomen ne yoru osoku neru tokoro datta desho?"
"odoroita watashi mo kakeyou to shiteta"
Kokoro nouragawa wo kusugurareteru youna
Hikareau futari ni shiawasena oto wo
Happii shisesaiza(happy synthesizer) hora ne tanoshiku naru yo
Namida nuguu merodei(malody) kanaderu yo
Tsuyogaranakutatte iinjanai? betsu ni
Jibun ni sunao ni nareba ii
Nanno torie mo nai boku ni tada hitotsu
Sukoshi dakedo dekiru koto
Chotto tereru youna tanjunna kimochi
