Intro
My first LUMIÈRE concert.
I went with the casual thought of just wanting to see them once.
But the moment I saw the four of them shining on stage, that thought vanished.
—And for just a split second, I felt like our eyes met.
It might have been my imagination.
Even so, my heart was stolen in those few seconds.
From that day on, I fell deep into the rabbit hole of LUMIÈRE.
