Wakakari shi hi o omou archaic smile
Roujin wa nani o satoru no ka
Togatta jinsei wa tsurai no ka
Keiken to iu mono o subete
Hohoemi no kate to suru no ka
Nigai omoide wa shouka suru no ka

Oh... how can you smile?
Where does that smile come from?
Oh... how can you smile?
Tell me how to smile.
[ Lyrics from: http://www.lyricsfreak.com/b/bonnie+pink/hohemi+no+kate_20799641.html ]
Shinayaka ni kakareta kotoba no otoshiana ni kidzuku ni wa mada
Wakasugiru yo na tooi yo na
Machinaka de denshoku ni kuru matte
Shuuchishin fukitobashite mitai
Hohoemu tame ni... dare ga tame ni?

Oh... how can you smile?
Where does that smile come from?
Oh... how can you smile?
Tell me how to smile... smile...

Itsu no hi ka tasogarete
Utsukushiku mieru no ka
Haiiro no toshi ni natte
Bara-iro ni hohoemetara ii kedo

Oh... how can you smile?
Where does that smile come from?
Oh... how can you smile?
Tell me how to smile.

Oh... how can you smile?
Where does that smile come from?
Oh... how can you smile?
Tell me how to smile... smile...
