※Who's that just who's that? I wanna know
Who's that just who's that?
Why didn't you tell me　何も教えてくれなかったの※
Who's that just who's that? I wanna know
Who's that just who's that?
いつまで逃げるつもりなの　now tell me who's that girl who's that
近顷妙に　you look so strange
何かをbaby隐してる样子　不审なベル不安を告げる
Baby,how can I ask you ｢who is it?｣
でもね信じている　真实确かめるまでは
I still believe in you　气のせい
でもねこの日曜　I saw you on the street
あなたと步くそのコ　Who's that girl
(※くり返し)
Who's that just who's that?　教えてよ
Who's that just who's that?
いつまで逃げるつもりなの　now tell me who's that girl who's that
I see your fase I see you look so pale
タバコに手を伸ばして　何も言わなくても
baby I found you tried to hide away
でもね信じている　真实确かめるまでは
I still believe in you　气のせい
でもねこの日曜　I saw you on the street
あなたと步くそのコは谁
(※くり返し)
Who's that just who's that?
Who's that just who's that?
いつまで逃げるつもり　my boy now tell me who's that girl who's that
忆えている　what you said to me
never gonna tell you lies
you told me never gonna say good bye
I still believe in you　愚かでも
だから笑ってウソだと否定して
Who's that just who's that?…
Who's that just who's that?
