four individuals in an indoor setting, potentially a classroom, suggested by the desks and chairs. Three people are seated at a table, each with a phone in hand. The person on the left is wearing dark clothing, the middle person is wearing a dark hooded jacket, and the person on the right is wearing a light-colored shirt. Another person in an orange shirt is seated further back near the window. A bottle of water is visible on the table. The room has two windows with blinds, with some plants visible on the windowsill. The floor appears to be wooden. The location is in Sofia, Bulgaria, based on the writing on the water bottle.
