Actually, grooming means trying to get someone to do something. Which does apply here indeed. As it does for most demon activity in fiction.
But when you add pedo, you mean sexual grooming, which isn't the case here. The demon wants his soul, and giving your soul to a demon is corruption of your soul. It doesn't mean sex at all. So you are wrong about that.
Of course there's yaoi written, but thinking of this first exchange as sexual is actually very deranged, it's like sexualizing interaction between two kids at the beginning of the story just because you know they'll be dating later, you know?
So please, your way of automatically sexualizing interactions between adults and children aren't normal. Seek therapy.
Girl don’t come after me for calling out problematic stuff.
Writing a story about a literal child and a man being in a relationship in the future is very problematic to me.
If their relationship would’ve been portrayed as non-sexual or a non-romantic then ok whatever but it literally says yaoi.
I get that it’s fictional and he’s a however-much-years old demon, but don’t come after me for calling it out.
