Place it after a sad violin cue builds up the tears, then cut to the reaction it interrupts. Follow it with a shocked oh-my-god moment to sell the change in mood, keeping this clip as the sharp turn between sympathy and comedy.
このサウンドについて
This is a short French voice clip, lasting about three seconds, in which a speaker tells someone to stop crying. The tone is blunt and exasperated rather than comforting, landing like a firm interruption in the middle of a dramatic moment. It feels awkward, funny and a little tense, the kind of line that cuts through over-the-top tears and makes the scene feel suddenly real.
