ROMANIZATION
[Siwon]
Nante nante kageki na situation
Sarani motto motto hamatte shimau darou

[Kyuhyun]
Saaiikai
Masu masumi wa kuna imeji
Kimi wa suikomare tada mita sare

[Leeteuk]
Saaiikai

[All]
Naisho naisho Opera
Odoru yo Opera
Utau yo Opera

[Eunhyuk]
Neeii kara kuru ni iko uka

[All]
Naisho naisho Opera
Kiwadoi Opera
Taito na Opera

[Leeteuk]
Saaiikara koregaii kara

[Donghae]
Neeiikara kuru ni iko uka
[ Lyrics from: http://www.lyricsmode.com/lyrics/s/super_junior/opera_japanese_ver.html ]
[Yesung]
Saaiikara koregaii kara

[Donghae]
Sashikomu hikari no shita dewa
Kimi no ai wa demo kasuka ni nijimu

[Ryeowook]
Sousa shuyaku haakuma demo boku de
Issai no yousha monai kimi wo toka su

[Siwon]
Saaiikai

[All]
Naisho naisho Opera
Odoru yo Opera
Utau yo Opera

[Sungmin]
Neeiinara hito nishiyouka

[All]
Naisho naisho Opera
Kiwadoi Opera
Taito na Opera

[Leeteuk]
Saaiiikara zenbu iikara

[Shindong]
Neeiinara hito nishiyouka

[Leeteuk]
Saaiikara zenbu iikara
