Letra da Música Happy Smile de Ai Maeda

Asa no hikari no naka demo ii yume mitai
Futari issho ni arukeba muteki yo
Amai kaori no suru hana watashitachi yo
Kyou mo ureshii yokan da wa fushigi ne

Dame yo! Iya yo!
Shikkari oshare shinakkucha

Itsu demo egao de iretara shiawase dakara
Kirei na mono takusan
Mawari ni atsumete okou
Yappari egao de iru no ga saikou dakara
Tanoshii koto ga suki
Hora happy smile

Nani, Mimi?
Niramekko shimasho
Okkee, makenai wa yo
Waratta hou ga make dakara ne
Un
Iku wa yo

Seeno, fuun, uwaa
Kuchukuchu kuchukuchu, hahahaha
Uwaaa, mou, hansoku yo, Parumon

Futari tasuke atta hibi wa mune no naka
Totemo shinpai shiteru no tooku de
Soba ni irarenakutatte tomodachi desho
Shashin no naka no futari ni uinku yo

Suteki! Kawaii!
Oki ni iri no basho e ikou

Tama ni wa namida ga tomaranai koto mo aru wa
Omoikiri naitara
Kokoro arawareteku wa ne
Tokidoki buruu na kimochi ni nattari suru wa
Sore demo shinjiteru
Saa happy smile

Itsu demo egao de iretara shiawase dakara
Kirei na mono takusan
Mawari ni atsumete okou
Yappari egao de iru no ga saikou dakara
Tanoshii koto ga suki
Hora happy smile
