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
