Place this clip underneath the whole scene as the background bed, then add a camera shutter at each photo change and a bell ding just before the final reveal to mark the turn.
关于此声音
This is a roughly 18-second excerpt of QKThr by Aphex Twin, a soft, fragile piano piece with a distant, airy quality and sparse, unresolved notes. It feels quietly sad and reflective, bringing a sense of nostalgia and calm introspection rather than drama. The track comes from the 2001 album Drukqs.
