Himitsu no tegami wo
Akibako ni kakushite iru basho
Tooi hi no kioku wo nozoitara
Chikadzuiteru 10(juu)dai saigo no hi made ni
Yarinokoshita koto ga mada arisou de aseru
Otona ni wa naritakunai to omotteta
Dakedo kansha shiteru
Thank you My teens
Utau koto bakari
Kuyashisa mo mata sugu uta ni shita
Sore dake de chikara ni kaerareta
Tomodachi ni wa sukoshi demo yoku omowaretai
Ki ni shite'nai tsumori na noni mieppari da
Atarashii deai ga yume wo sasaeta
Dakara kansha shiteru
Thank you My friends
Otona ni wa naritakunai to omotteta
Dakedo hatachi ni naru
Thank you My teens
