I didn't know (or forgot) that there was a
Hazel in The Fault in Our Stars, so I assumed
Hazel coming back was partly because of the popularity of witchy aesthetics? I recently watched a video about people trying to capitalize on that "witchy aesthetic" thing by interviewing real witches but making the whole thing into clickbait. There's also the whole cottagecore thing which overlaps with the witchy thing and I's expect both to influence the popularity of
Hazel.
