An intimate portrait of depth beneath the surface

Let us return to the title. The original proverb— still waters run deep —implies that quiet people have profound thoughts. But Daria and Sergei subvert this. Their waters are still, but they are not running deep ; they are running new .

Daria (32, a graphic designer) and Sergei (34, a carpenter) live in a small Russian city. They are deeply in love but their sex life has become quiet, predictable — loving but passionless. A friend mentions Lustery , and Daria becomes curious. Sergei is hesitant at first but agrees, thinking it might reignite something.

The phrase “still waters run deep” is a proverb meaning a quiet exterior often conceals a passionate nature. By modifying it to Daria and Sergei—and by extension, the Lustery team—are making a statement about long-term relationships.
