First published as one-shot titled "Kinou no Akane" (きのうの茜) and later as two chapters titled "Ashimoto no Arukikata" (足下の歩き方)—these are included in volume 1 as chapters 1~3. Afterwards serialization started from Fellows! volume 22 under the title "Kobito Hiyori" (こびと日和). Since Fellows! volume 26 (2012/12) the series has been serialized under the current title.
