Das Bild zeigt eine Frau, die auf einem Sofa sitzt und die Heizkostenabrechnung von ista liest. Sie hat langes blondes Haar und trägt eine schwarze Brille. Ihr Oberteil ist ein blaues Hemd, dazu trägt sie eine braune Hose. Während sie die Heizkostenabrechnung in der linken Hand hält, ruht ihre rechte Hand an ihrem Kinn. Sie blickt direkt in die Kamera. Das beige Sofa, auf dem sie sitzt, erstreckt sich über das gesamte untere Drittel des Bildes. Auf der linken Seite liegt eine weiße Decke über der Rückenlehne, davor lehnt ein gelbes Kissen. Im Hintergrund sind verschiedene Möbelstücke zu erkennen, die auf ein Wohnzimmer hinweisen: Rechts stehen eine Stehlampe und ein Regal, in der Mitte führt eine offene zweiflügelige Tür in einen weiteren Raum mit Bücherregalen. Der gesamte Hintergrund ist unscharf.

The picture shows an intimate moment in a brightly lit room. In the foreground is a couple in a loving embrace in front of a large window. The man is wearing a brown top and beige trousers, while the woman is wearing a light-coloured top and dark trousers. Both people are standing barefoot on a wooden floor, with the man standing slightly behind the woman and embracing her tenderly. The window, which takes up most of the background, allows plenty of natural light into the room and offers a view of a wooded outdoor area. The sunlight streams through the window and creates warm rays of light in the room. To the left of the picture, near the window, is a table attached to a wall. There are two small objects on the table, presumably salt and pepper shakers. To the right of the window is a large houseplant in a white flower pot. The plant is clearly visible and lends the room a natural atmosphere. In the right-hand part of the picture, further in the background, there is a piece of wooden furniture that looks like a wine rack or a small shelf. There are a number of objects on the shelf, including a framed picture and other decorative items.
