I like the author's plots but it consistently involves grooming :(

Hey, genuinely asking, why do you think this one involves grooming? Or are you talking about other works and not this? I've only read 'Hearty' by this author and that didn't involves grooming.
From My understanding grooming involves a vulnerable kid/teenager and manipulation to abuse them. I didn't see any of those signs here so I'm really confused if I missed something.
