In a future where most of the land is submerged in water, streetlights that once illuminated the roads now shine in the middle of a lake, and people sip warm sake while enjoying the glow. It is a village of romantics who live slowly and stylishly. At the heart of this village is a café run by Alpha. Coffee refills are a given, and leisurely conversations with the café owner, Alpha, are essential. It's a comic that feels like a comfortable rest.
