Nee Naisho ni shite ne Mune no oku ni hikaru
Houseki yori kagayaku wa Himitsu no kimochi wo
Dare mo kizukanai you kokoro no umi sodatsu
Sekai de tada hitotsu na no Himitsu no kimochi ne
Me wo tojiru tabi omoidasu no wa
Egao to yasashii koe
Kitto ienai demo wasurenai
Mune wo utsu kono kodou
Nee Naisho ni shite ne Kokoro no atsui kaze
Anata ni dake uchiakeru Himitsu no kimochi wo
Anata to issho otona e no michi
Ippo-zutsu susunde kita
Da kara hanasu no Dare ni mo naisho
Hajimete no koi da kara
Nee Naisho ni shite ne Kokoro no oku ni hikaru
Sekai de hitotsu dake na no Himitsu no kimochi wo
Himitsu no kimochi wo
