R was sixteen and L seventeen when they first met. It was love at first sight. They promised to love each other no matter what, and have kept this promise for the last five years. Each of them has had little crushes on other people, and they have broken up several times. Nonetheless, they have never stopped loving each other. After each crush has played itself out, L says to R, "It doesn't matter who else you love, I know you'll always love me best."
