Three people and a dog are inside a Sofia Metro train

Three people and a dog are inside a Sofia Metro train. The person in the foreground on the left is a man with a shaved head wearing sunglasses and a black t-shirt. He has a black dog with a pink harness resting on his shoulder. To his right is a woman wearing glasses and a blue shirt, looking down at her phone. Behind them, a man with short dark hair and a beard is leaning forward, pointing downwards with his right index finger. The train interior shows teal-colored poles and overhead signage indicating metro stations.
