Ayayaya Sweet Emotion
Ame ni fukarete sugata furu yume
Tada no koe ga warai tte yoi nara
Aoi sora ni uchi ha su nai yori
Hoshizora ni kimi ga aru
Ayayaya Sweet Emotion
Utauyo Kimi no koe ga
Sono hitomi ni ukabu yo
Hana ni nurete kite mo ii
Sono tame ni boku wa waratteiru
Chikatta furi tsukarete yuku
Mizuumi no sora o miru yo
Dareka no tame nanka iru koto ga
Kimi to minna ga deatta hi mo
Kimi ga suki dakara

Boku wa ai o sakenda kimi no sekai de
Chikatta furi tsukarete yuku
Kimi no koto ga nai koto o

Chikatta furi tsukarete yuku
Kimi no koto ga nai koto o
Sweet Emotion いつもそばにいても
Boku wa kimi ni natteiru
Sweet Emotion いつもそばにいても
Sweet Emotion いつもそばにいても。
