Let's run !

A man in a black shirt looks down, then the scene cuts to a woman in a red shirt looking shocked, followed by a man in a red shirt clapping, then a man in an orange vest looking surprised, then a man in a black shirt and orange vest holding a red fan, then a woman in a green shirt holding a black object, all reacting with shock or surprise to an off-screen alarm. The setting is a classroom or indoor space with various people.
