"Have you heard of the butterfly effect?"
"Yeah. Why?"
"Nothing. I just wanted to say that if a single sentence can start a war, then
"a single glance is enough to make you fall in love with someone."
The war will never end, and our love will never come to anything. Like a rainbow that never appears after the rain, our fates intertwine and change, but we still can't exchange them for a promise.
-- "Forget it. We'll leave it to fate."
-- "Don't say something so trite. I don't believe in fate."
-- "If we win this battle, we'll get married."
-- "And if we lose?"
-- "Then it means I'm dead. After I die, don't be sad or grieve. Don't be stupid and spend your whole life mourning me.
"Find someone and marry him. Go somewhere safe and far removed from the world, have a bunch of children, and become a teacher who teaches only your own kids. Then watch them grow up and become mature, watch them stand on their own, watch them gallop through life.
"I only want to share those things with you. Since I'm dead, take my share of happiness and our future with you. Live bravely, without regrets. Then wait twenty or forty years for me to come back and find you. If twenty or forty years aren't enough, I'll find you in our next life."
Even if fate plays cruel tricks,
Even if we reach the end of the road,
I will remember you at my side,
Cutting through every obstacle for me, bleeding on the battlefield for me.
Even in the endless night,
You will fear nothing.
You will always be that ray of light for me,
Able to illuminate heaven,
Able to promise me the dawn.
