Kaoru has spent years studying all the behavioural patterns that make up Nanjo Kojiro: the pink flush of his ears when he’s lying and the way he reaches up to ruffle his own hair when he doesn’t know what else to do with his hands, how he takes in an extra-deep breath before blurting out something he’s kept bottled up. How sometimes he stops just before opening his mouth, and how Kaoru always wishes he wouldn’t.

Kaoru and Kojiro learn the complexities of going long-distance.
