Café Trivia

question:

Why are Mitsuru and Kazuya sleeping under the table in Episode 5?

answer:

It's a kotatsu, or heated table. The table has a heater built into the underside of the table top and can be quite warm. These tables are often used in the house in Japan during the winter since there is no central heating or insulation in the houses in Japan. So the warmest place to be would be to sleep under the table.
