If it is a sin, where's my existence?

Dokonimo nai no yo atashi no tomoshibi
Zurui wa... kono mama anata wa shiranai

I'm falling down and down.

Tomadoi setsunasa kurushisa samishisa mo subete motsurete omowazu
"Aishite iru" nante tsubuyaketara...

If it is a sin, where's my existence?

Anata no tabako no kemuri ga chikazuku
Atashi wo hidoku kyozetsu shite yurasanai

I'm falling down and down.

Kuchihatete kiete shimau kajitsu no you ni ima mo
Munashiku anata wo omoeba omou hodo tokeochite...

Somebody tell me.
Is this a sin by loving him?
I want you. I need you.
I can't stand it.
Don't know what to do.

Memai warui yume mune zawagi obiete iru no
Atashi no kuchibiru ga omowazu morashita tsumi wo...
Onegai... anata no ude no naka ni wa mada ima mo
Atashi no ibasho ga kakusarete iru kara
Nee...
Yurushite...
