Geheime liefde Kasumi-san 1

Ryoji is studying and lives fairly close to his steprelatives. When their house is broken into, he is asked to move in with his steprelatives so that Kasumi would feel safe again. Because he is often broke anyways, he gladly agrees to do so. But he soon realizes that Kasumi's husband is rarely home and that Kasumi in turn often feels very lonely. So because she is also not satisfied sexually, a new job comes up for Ryoji quite quickly...
