Naruto - Joke Box (Doujinshi)

Pairing: Kakashi x Iruka

Vol 7 (2005)
Main story: In Kakashi's absence, Iruka ponders the status of their relationship.

Although this story stands fine on its own, it is actually the middle part of three loosely connected books, and you may wish to read them in order. The first book is "Haru Urara", then comes this untitled story in "Joke Box 7," followed by the third book, "Under the Sun, Under the Cherry".

Reprinted in volume 7 of Chikadoh Sairokushuu
