Nanigenai chiisana dekigoto
Sukoshi dake shiawase ni naru ne
Ah futari de sugosu Day By Day

Akaku natta hoppeta
Itsumo to chigau taido
Ushiro metasa mitai na mono wo
Doko ka kanjita

Tatoeba kimi ga
Me no mae kara inaku naru to
Karakara ni kawaki kitta
Kokoro ga iyasarenai

Nanigenai chiisana dekigoto
Sukoshi dake shiawase ni naru ne
Muboubi na negao miteru toki
Me ga naku naru hodo warau toki

Day By Day…
Day By Day shiawase ni narou
Mou sukoshi uso mo umaku tsukou
Tsukiai datte iroiro aru shi
Ah futari de sugosu Day By Day
