The age gap seems exacerbated by the artist. Not trying to defend him completely, but it is a four year age difference. (4th grade vs 8th grade). Still not kosher though… particularly with how he was describing him as a kid.
It’s not only the age gap that makes this disgusting, but the mentality gap. A 9/10 year old is a lot less mentally developed compared to a 14/15 year old. It doesn’t matter that he was in 8th grade, he still deserves to be murdered. This goes for when this happens in real life too. Predators and groomers deserved to be lynched!!
It’s like a seinen artist decided to write yaoi one day.
