@nootnoot001 I've been wondering the same thing, and actually was just going to reject daddy. But I think I realized what's going on in chapter 19.
In the last timeline daddy sent Max in to save his daughter since Max clearly would do whatever he wanted. But Jubelian didn't know Max was there to help her or that her daddy wanted to help her at all, so she killed herself. And look at the different frames in chapter 19 when it shows daddy's face from a neutral perspective vs Jubelians perspective. When he's shown from a neutral perspective he looks happy, but when it switches to her vision he's all dark and covered in shadow. And she puts words in his mouth too whenever it shows him from her eyes.
It looks like she's an unreliable narrator, and whenever we see the world from her eyes it's a little twisted from her expectations. He might've still neglected her, but it isn't as bad as it seemed.
