Lyrics:

Kimi ni deatte kara suki ni natte
Taisetsu na mono ga fueteku
Te wo tsunaida yuugure happy rainbow (rainbow)
Kono love song (love song) love song
1000nen ga sugite mo kimi ni all my love
Kimi ga iru kono sekai mamotte ikitai mirai
Zutto (kissing the sun) kissing the sun
Kimi ga warau toki wa sekai mo tanoshii no sa
Zutto (kissing the moon) kissing the moon
Come on kissing the sun
Kowaresou na mono de afuretatte
Boku ga iru kara daijoubu sa
Namida no shizuku mo fuwari to
Sweet candy (candy) change your tears
Boku wo shinjite ima kimi ni all my love (baby my love)
Kimi ga iru kono sekai mamotte ikitai mirai
Zutto (kissing the sun) kissing the sun
Kimi ga warau toki wa sekai mo tanoshii no sa
Zutto (kissing the moon) kissing the moon
Kono kimochi todoite with me with me boku dake no baby
Kimi no hitomi no naka boku wo utsushitsuzukete ite
Kimi ga iru kono sekai mamotte ikitai mirai
Zutto (kissing the sun) kissing the sun
Kimi ga warau toki wa sekai mo tanoshii no sa
Zutto (kissing the moon) kissing the moon
Kimi ga iru kono sekai mamotte ikitai mirai
Zutto (kissing the sun) kissing the sun
