Two little people, Haku Mei and Miko Chi, live in the forest. During the day, they spend their time working and playing, and then... what happens next? The night flows slowly, quietly, and with a touch of melancholy. There are things that can only be seen at that time. This fourth volume is filled with episodes depicting "nighttime pleasures," such as night trains, moonlit evening drinks, late-night coffee, and the night before a festival!
