Layer and Renka are both in the prime of their working lives and are busy, so they rarely have the same days off, and even though they live together, they miss each other every day. However, on their day off, they spend time together for the first time in a while, lazing around, taking baths together, cooking meals together, and then they start making love to each other in the afternoon. Because they are close friends, their everyday lives are just happy.
