It is a story about separation, pain, and emotions before love.
Looking back on the times when we had to break up, I discover what true love is in the solitude and anxiety I felt while facing it.

Our meeting has ended.
I'm going to start writing this eagle.
Only after all the light had been consumed, like ashes, did we face each other in darkness.
At some point, we felt that our hearts were no longer burning, that we were both fading away from each other.
You from me, I from you, faded away like a flame that can never be rekindled.

--- From the text

Love is the pain of your own heart while listening to the other person's heartbeat.
