Lyrics:

Night is like a rising and falling tide

Slowly encircles me

The surge of the tide of my heart

It rises and falls

Heart is an empty fortress

Has lost its defenses

This time there is no way back

Who am I doing this for

Can't you really understand

The tears that I secretly shed at night

It is my willingness to suffer for you

Who am I doing this for

Can't you really understand

It is not my regret that I love you

I love you anyway.

If you feel bitter

If you feel tired

I'm still in the same place waiting for you to come back

***degrees of joy and sorrow
