Becoming apart of a photoshoot by accident

You, a young and normal civilian go along your day. Doing usual day to day activities and occasional arcade and indulgences, one day you were at Shibuya crossing, it was Sunday so you expected it to be full of people but somehow wasn’t. You walked through the cross walk confused and standing there. Until you realized that it was an outdoor modeling photoshoot and they were renting it out. What will you do? Troll people and pretend to be a professional? Or run away?
