People have really been talking about this so let me put my two cents in,
First of all No, people marrying petite flat chested women isn't pedophilia, some people really are stupid by thinking only euro-centric beauty standarts are okay and the rest is pedophilia.
And secondly, you are right, grooming is "Child grooming is befriending and establishing an emotional connection with a child, and sometimes the family, to lower the child's inhibitions with the objective of sexual abuse." so your definition is right. But people love using big words to look smart, as you can see he is not preparing her for some sexual act so it is not grooming.
Lastly, who cares, this is a manhwa and these characters are not real. So the author can write whatever they want.
IMO It’s only considered grooming when they are raised with that intention since young, from the very beginning. And no you can’t call them a pedo unless they are feeling romantic love or thinking/actually committing sexual acts or harassments to the young child
Legal lolis don’t count
Okay I need to get this straight but isn't grooming about specifically waiting and preparing a child to do sexual favors for when they are of legal age or near that? Isn't a predatory behaviour already a existing thing, before even getting to know the person?
I need to get the concept right cuz honestly, the majority of English speaking people (imma be a bit prejudiced here but I'm betting it's mostly americans) just throw around terms and change the meaning of things all the time so I'm not sure what's considered what anymore. E.G. if a man is going out with a petite woman with flat chest and all that, is he considered a pedophile? Cuz I've seen this happen and I don't think it's pedophilia or else a small woman could never get married peacefully.
Lots of people saying they end up together and all but if that does happen, is that really grooming? If in the future, by chance, he falls in love with the amazing woman she's become, not even thinking about such things before she reaches a certain age, is he reaaally a pedo or a groomer? I think it's bullshit, but please let me know if I'm interpreting the term wrong
