Place this clip as the immediate reaction beat right after the disappointing reveal, then follow it with a Kiko laugh to flip pity into teasing. For a longer bit, precede it with a gasp effect and let the laugh close the sequence.
关于此声音
This is a very short voice clip of someone stretching out the word 'lástima' in a drawn-out, exaggerated lament. It lands as mock pity rather than real sympathy, turning a small disappointment into a teasing, over-the-top reaction that feels both sorry and amused at the same time.
