I just went back through all the previous chapters and yes, her hairpin is different in every one and these are the details I live for. thanks for translations!! loving this series.
i went back for a different purpose: to find all the cases where her hairpin was inconsistent!
found exactly two times that the hairpin vanished for a single panel:
chapter 4 page 21 and chapter 6 page 19
the shape of the hairpin is consistent tho
