Doushite itsu datte sou dareka no sei ni shite sa
Genjitsu kara nigeru no mitometakunai'n da yo ne

Ima no jibun ga daikirai de yowai jibun wo kaetakute
Soredemo kanaeru to chikatta kaware sou na ki ga shita

One day
Mama ga kureta pureiyaa kara nagareta first love ima demo my treasure
A dream come true kanaetai mono ni deaeta te ni ireta no
One day sotto namida ga dete kidzuku'n da totemo shiawase da to
Koukai wa shitakunai dakara chikau yo I will kanaeru to ooh

Inside of my heart
Inside of my heart

Douse muri dakara to saisho kara kimetsukete wa
Nanimo umaku ikanai nanimo hajimari yashinai desho

Sonna yume nante kanawa nai kokoro nai hitokoto de naita
Dare ni mo yuzure nai omoi mou ichido kidzuita yo

One day
Namida kaerimichi hitoshirezu nagashita tada kuyashikute
Hitori natsu no owari nijinda sora te wo nobashita
One day you will know hoka no dare ni mo mienai perfect sky soko ni hirogaru yo
Only you kagi wo nigiru open the treasure box jibun shidai ooh

One day
Mama ga kureta pureiyaa kara nagareta first love ima demo my treasure
A dream come true kanaetai mono ni deaeta te ni ireta no
One day sotto namida ga dete kidzuku'n da totemo shiawase da to
Koukai wa shitakunai dakara chikau yo I will kanaeru to ooh

Inside of my heart
Inside of my heart
Inside of my heart
