Maybe she wasn't satisfied and asked to record it again. It happens all the time after getting the draft song back. Maybe she wants to have a detailed MV. It could be a lot of things. We know how much she can obsess about a lot things. Her first original song will be one of thos things that would highly likely trigger her autism.
recording hours of passionate breeding clock sex for Kronii
she watches the recordings
”Nope, not good enough, do it again”
and so on and so on and so on as an excuse for constant sex
I love my hikki nympho clock!
Ngl the idea of recording sex with a shy, awkward, repressed dork like Kronii just so she can watch it herself later is hot as fuck.
