I feel like those types of stories reflect the author. They're probably yearning for familial love to fill the void left behind, especially if their parents doted on the other siblings. I'm not generalizing, just observing my friends who are ao3 authors. They often have a certain chapter where I can sense that they pour their feelings into that character because they relate to it.
This is the best family centric manhwa I’ve ever read! I especially love how the parents love their children equally. You don’t understand how upset I get when I read similar stories and see the parent(s) only doting on the mc while ignoring/ tolerating their other children. So seeing the mom & dad outwardly (and verbally) express how much they love the other two kids is such a welcoming sight.
