No, sorry. maybe you read his whole novel but you don't understand it. Don't put all the blame on Ash, he and Koi did what they could. *spoiler* His partner almost died trying to raise their children normally, but they later find out that something's wrong with their children, especially Greyson. No perfect parents exist even in real life, don't expect fictional parents to be one. Σ(  ̄□ ̄||)
Take note: even in real life, parents would love their "special" kids to be treated normally.

The more I read , the more I'm convinced that Ashley shouldn't had Kids at all.
Dude couldn't handel a Normal Child like Chase
And It even worse when Grayson
Knowing that you hit me with famous Line " you don't understand him ,since you haven't read His Story ...." I did read His Story and His Parent's as Well. and I unterstand where He comes from ... and that make me despise him even more
He didn't put that much effort into raising His children , Not as much as He did for His Partner .
