Oda seems to hate being a father and husband, just look at how little his own kids and wife see him. Blud was working up to 21 hours a day and got himself hospitalised. He writes all these sympathetic stories of adoptive parents being amazing parents, yet the actual parents being terrible to their own kids.
He's missing out on spending time with his daughters, watching them grow up, being there for them and being a father for most of the time, so he can work on a fucking comic series for teenagers that has been going for almost 30 years now too. Hes probably dragging out One Piece so he can be away from his wife and marriage too, maybe being a father as well /s.
The writers barely disguised fetish/issues. Vivziepop does a lot of similar shit in her series too. To the point people are noticing how ridiculously abundant and thus unavoidable it is now.
