Selene, who reports trivial discoveries. Fiona, who is kind and caring but has recently become a little mischievous. Lumiere, who wants to show you one unknown thing after another. Nereia, who notices your loneliness from a short distance away.

No mission to save the world, no special powers. After school, messages, shopping, walks, and the occasional small anomaly. A romance story where the distance between you and these four changes in different ways through the accumulation of daily life.
