Aside from "Setsugetsuka", this collection also includes "Utsukushii Mono" (Beautiful Things), "Dousei Yokka" (One Roof, Four Days), "Warau Zanzou Sunny" (The Laughing Afterimage, Sunny), and "Koi Otoko" (Man in Love).
I read the Indonesian translation, so not really sure if it's translator's fault or it's been bad from the source--but I'm inclined towards the latter; but the dialogues are bad, really juvenile in writing.
