Kabe wo tataku ude no itamiga
Boku no kimochi atsuku saseru yo
[yoochun]
Easy come easy go raku na geemu ja
Negai no reberu ga mitasarenai kara

[junsu]
Just now or never koko kara saki wo
Kimeru no wa kimi shidai
To do or die nidoto wa nai
Kono chansu boku nara mayowazu just do it

[all]
No pain no gain
Tatte yukuyo suguni
Kizuita toki kara
Yume wa ugoki hajimeru
No pain no gain
Ashita e no kabe wa
Jibun no ryoutede
Uchi yaburunda ima back hand blow

[yunho]
Nanimo sezuni nayande itemo
Yami no naka ni hikari wa konai
[changmin]
Sukoshizutsu demo kowashite yukeba
Kabe no sukima kara hikari wa sasu no sa

[yoochun]
'cause you're not alone tatakau toki wa
Chikara awaseru kara
So don't give up itsu no hi ka
Mukou gawa ni deguchi ga hirakareru yo

[all]
No pain no gain
[junsu]
Kagayaki no basho wa
Sugu sobani aru yo
Yuuki dashite ikiyou
[all]
No pain no gain
[junsu]
Sono kotae koso ga
Darenimo makenai
Kimi ga mitsuketa puraido

[jaejoong]
Shinjiteru yo kimi wa kitto dekiru
[changmin]
Me no mae no the wall is myself
[junsu]
Teki wa ima koko ni iru jibun dakara

[all]
No pain no gain
Tatte yukuyo suguni
Kizuita toki kara
Yume wa ugoki hajimeru
No pain no gain
Ashita e no kabe wa
Jibun no ryoutede
Uchi yaburunda ima back hand blow
No pain no gain
Kagayaki no basho wa
Sugu sobani aru yo
Yuuki dashite ikiyou
No pain no gain
Sono kotae koso ga
Darenimo makenai
Kimi ga mitsuketa puraido
