さよならをおしえて - Sayonara O Oshiete/It Hurt to Say Goodbye
I’ll wait till you love me
I’ll wait for you, goodbye
I’ll wait forever until you love me
I’ll wait for you, goodbye
Even if a disaster occurs and muddy waters run
Turning the whole city into ruins
I’d open the heavy doors of the shelter
To call your name out loud
Good-bye
Even if I die in an accident
Don’t rest assured
I’d come back as a ghost
To call your name out loud
Good-bye
