SILKS-113 Happiness, As A Matter Of Course.

Tiêu đề ban đầu: SILKS-113 当たり前の、幸せ。

Reya and Renka are both busy working, and their days off are rarely the same, so even though they live together, their lives are not always the same. On their first holiday together in a long time, they spend time together, take baths together, cook meals together, etc... Then, they begin to seek each other out and make love from noon onward. Because they are such casual friends, they are simply happy in their normal everyday life.
