First Version
SHA LA LA Some day in the future I will, for sure, hold it in my hand Let it softly set ablaze A light in your empty heart.

The "impulses" of wanting to meet you, the "innocence" of wanting to cry, the fireflies have gone into the blaze of the summer to never come back again.

You remained silent and left me a kiss, pained and hurt, I nodded my head. your life flickered like a light, it was so sad.

SHA LA LA Some day in the future, I will, for sure, hold it in my hand. let it softly set ablaze A light in your empty heart.

SHA LA LA My sweet, lovely dear, I can see you too now. The dazzling moon will softly, Illuminate the morning day.

Strongly, strongly shine on.

Second Version
Sha la la I know that someday. I'll find what I'm running after. Let the light shine in your empty heart. and set your soul ablaze.

The desire to see you again is so pure it makes me weep. The fireflies have flown off into the summer sky never to return.

You left me with a silent kiss goodbye and hurt and upset, I still nodded my head left alone, trembling and sad.

Sha la la I know that someday. I'll find what I'm running after. Let the light shine in your empty heart and set your soul ablaze.

Sha la la Oh my beloved. I can still see your safe. as the moon's dazzling light illuminates the next day shine strong, shine strong!
