Relaxed and cozy dinner comic about hanging out in a traditional Japanese home in the boonies with a traditional in-floor furnace. They make something nice on the furnace, the boy and the older girl feel a little bit awkward, repeat.

If ever an artist was in love with their subject, the artist is in love with this heroine. It bleeds from the panel.
