Itsuka konna hi ga kuru darôtte koto wa
Wakattetan da nantonaku dakedo
Amari ni mo jikan ga hayasugita kara
Kimi wa sukoshi tomadotta dake sa

Sô yasashiku ore wa kimi o kizutsuketeiku
Tooi fun & games
Nee ima demo
Ano hi no koto oboeteru kai

Sayonara december furueru sono mune no kodô
Soshite kimi no koe shika kikoenai
Kogoeteshimaitakatta ano mama
Wasurenaidekure yo oh… sunnyday story

Sô yasashiku kimi wa ore o kizutsuketeiku
Tooi fun & games
Nee ima demo
Ano hi no koto oboeteru kai

Sayonara december furueru sono mune no kodô
Soshite kimi no koe shika kikoenai
Kogoeteshimaitakatta ano mama
Wasurenaidekure yo oh… sunnyday story

Are kara december kuru hi mo kono mune ni nokoru
Itsuka no kimi no koe ga hanarenai
Koboreteshimatta ano hi o
Wasurenaideiru yo oh… sunnyday story
