>>8614899after listening for a number of times I can say this:
1. Slightly before the sneeze there are some other sounds in the distance, while Kronii is talking (
https://youtu.be/6WFU2wzPKfA?t=7078). to me it sounds like someone is using some electronic device. The character of these sounds (the compression/noise gate)
and also the perceived distance matches the character of the sneeze. In order for this to be Kronii's sneeze she would have had to move like 10 metres away from the mic.
2. No it doesn't sound like a granny sneeze, rather a girl with a high pitched voice sneeze. Maybe it's her younger sister. Maybe it's her gf.
3. Look at her eye movement right after the sneeze. She definitely heard it and panicked a bit. Her eyes were pretty relaxed and didn't move much prior to the sneeze.
My conclusion is that she lives with roommate/sister/gf. Pretty much a nothingburger.
