このサウンドについて
A very short voice clip of someone saying the Italian word senzapensieri, lasting just under a second and a half. It lands as light and unbothered, the verbal equivalent of shrugging off stress and choosing an easy mood instead, which makes the delivery feel cheerful rather than dismissive.
