Himitsu ~prologue~

Itsuka kiita monogatari wo (ima mo)
Kimi wa zutto shinjite iru nda ne
(Hora) kyou mo sekai wa himitsu de michiteru no ni

(Sore wa)
Tatoeba tsuki no uragawa no keshiki ya
Hanabira ni kakureta mitsu no aji
Watashi ga mune ni hisometeru kimochi mo
Hirari himitsu hitotsu

(Kimi to)
Itsuka kiita monogatari ni (hontou wa)
Daremo shiranai tsuzuki no peeji ga aru
(Nee) shiritai? Tsuite kite oshiete ageru yo
(Te wo tsunaida nara saa yukou yo mori no oku made)
