Bài hát: Yakusoku No Melody - Masaaki Endoh

Ima mabuta tojitara sobani kanjiru
Kimi ga kureta kotoba kuyashinamida mo
Nagare nagare mata kisetsu wa sugite
Kuri kaesu...

Nakitai toki wa hora naite ii yo
Tamerau koto nante shinakute ii yo
Kanashimi hareru made koko ni irukara
Kimi no mikata de irukara

Hikari no sasu mirai e
Soko ni nani ga aru ka wakaranaikeredo
Nani mo kowagaru koto wa naikara
Mayowazu ni sā ikou

Forever my friend zutto zutto
Negatteru kimi no egao kagayaku yō ni
Itsu made mo itsumo itsuno-bi mo
Hitori janai don'na toki mo
Onaji uta ima mo hibiku tsunai deru
Yakusoku no melody
Oh you're my best friend

Shiawase ni naru tame hito wa umarete
Shiawase ni suru tame tsuyo-sa oboeru
Dare mo hitori dewa ikite ikenai
Yowa-sa o kamishimenagara

Kogoeta te o kasanete
Ano hi na kushita yume no kakera atsumeyou
Meguri ai wa fushigina kiseki shiawase kanadeyou

Forever my friend zutto zutto
Kawaranai tatoe betsu no michi o erabi
Hanarete mo mata meguri aeru
Hitori janai itsumo itsumo
Onaji sora no shita omou kanji teru
Kitto daijōbu

Forever my friend zutto zutto
Negatteru kimi no egao kagayaku yō ni
Itsu made mo itsumo itsuno-bi mo
Hitori janai don'na toki mo
Onaji uta ima mo hibiku tsunai deru
Yakusoku no melody
Afure dasu melody
Oh you're my best friend
