Lyric

"It Wasn't a Mistake" is a gentle J-POP ballad about learning to accept your past -
even the wrong turns, even the tears -
and finding the courage to say: "That, too, was part of me."

It's a song for those who have doubted themselves.
Who've compared. Who've questioned everything.
But still kept walking, one uncertain step at a time.

With its chorus-first structure and no outro,
the song unfolds like a quiet realization -
that progress isn't always loud, and healing isn't always fast.

This is a reminder that even if you've stumbled,
even if you've lost your way,
you were never truly lost.
