[Verse 1]
How do I say goodbye
Hayasugiru wakare ni
Kokoro ga tsuite ikenai
Hitori de aruiteyuku jishin nante nai
It's so hard to say goodbye to yesterday
Yesterday, yesterday

[Verse 2]
Saigo no kaiwa wo omoidasu
"Tsuyoku ikinasai hitori ja nai kara kowaresouna toki wa
Mune no naka wo mite soko ni watashi wa iru kara", ooh
Jyuu nen ni jyuu nen go mo
Ima mitai ni senmei ni anata wo aishitsuzukeru

[Verse 3]
And I'll take with me the memories
To be my sunshine after the rain, oh yeah
It's so hard to say goodbye to yesterday
Yesterday, yesterday
It's so hard to say goodbye to yesterday
Mmm
