Nee ki ni natte tomodachi ni kiitemita n da
kimi ga chotto inai aida ni...
bokura ga sotto naisho de atteiru koto
dare ni mo hanashiteinai yo ne?
thu-lu-thu thu-lu-thu doko de nani o shiteite mo
thu-lu-thu thu-lu-thu boku dake no kimi
    Hey, I was wondering, I tried asking a friend
    When you weren't around for a bit...
    The fact that we are meeting in secret
    You haven't been telling anyone, have you?
    thu-lu-thu thu-lu-thu No matter where you are or what you do
    thu-lu-thu thu-lu-thu You are mine alone

Moshimo kimi to minna ga iru rouka de
guuzen surechigatta to shitemo
boku no koto o furikaettari wa shinai de
sowasowa shita me de minai de...
thu-lu-thu thu-lu-thu kimi no sumashita kao
thu-lu-thu thu-lu-thu boku dake no mono
    Say if, in the hall with everyone around
    should we pass each other by coincidence
    Don't turn around to look at me
    Don't look at me with nervous eyes...
    thu-lu-thu thu-lu-thu Your composed expression
    thu-lu-thu thu-lu-thu is mine alone

Dare mo kimi no kokoro ni wa sawarasetaku wa nai kara...
sono kieteshimaisou na bokura no himitsu ni
dareka ga fureteshimau to kitto kowareteshimau kara
boku ga eien ni sore o mamoru tsumori de iru n da
    Because I don't want to let anyone touch your heart...
    Should someone touch our secret that seems
    about to disappear surely it would break apart so
    I intend to protect it for eternity

Nee ki ni natte denwa o shitemita n da
nandaka ukanai kao shiteita shi...
moshikashitara dareka ni bokura no koto
soudan shiteitari shinai yo ne?
    Hey, I was wondering, I tried calling
    I even looked a little depressed...
    It couldn't be that you are asking someone
    for advice about us, could it?

Nee kono mama bokura owatteshimattemo
nanimo nakatta to ieba ii
nee kono mama himitsu de isae sureba
iroiro to tsugou mo ii shi
thu-lu-thu thu-lu-thu sore wa kimi no tame
thu-lu-thu thu-lu-thu soshite boku no tame
    Hey, even if we end it just like this
    We should just say that nothing happened
    Hey, if we just leave it a secret like this
    It's convenient in many ways
    thu-lu-thu thu-lu-thu That's for your sake
    thu-lu-thu thu-lu-thu and for my own sake

Daremo bokura no sekai ni wa sawarasetaku wa nai kara...
sono kieteshimaisou na bokura no himitsu ni
dareka ga fureteshimau to kitto kowareteshimau kara
bokura ga eien ni sore o mamoru tsumori de iru n da
    Because I don't want to let anyone touch our world...
    Should someone touch our secret that seems
    about to disappear surely it would break apart so
    I intend to protect it for eternity
