Reading between the lines is a good thing lol. All stories have a lot more to say than the plain text due to implication, tone, references, etc. This is what forms a story's "subtext," and "reading between the lines" is paying attention to the subtext instead of accidentally skipping it.
Like everything in life to much of something is never a good thing. It good to read between the line to go deeper into the story, explores it meaning to find what missing between all the subtexts. But go over than that it may lead to projecting.
For example, the subtext of the last two chapters is that Yvonne's father is a man you should like, despite having some pretty clear flaws like heteronormative biases and looking at Elsa as a useful resource. The people rubbed the wrong way by that are not making shit up, they're disagreeing with the positive framing that presents those flaws as things that can be part of a good likeable character, a good likeable man.
Even a saint will has unfavourable side. Judging a person or an event without full context of the matter can lead to everywhere. It ok to feel offended about something but only an open minded can help reveal a new aspect of that same thing.
I think based on the regular text of this arc that the dad is an ignorant dick and needs to be sat down and educated if he can ever be trusted to do right by Yvonne and Elsa. Unfortunately, the framing implies at the very least that Yvonne and Elsa don't see it that way. That's sad for them tbh. They should expect and get better from their parental figures.
We as an reader can project our thoughts and emotions that purely basing on our understanding of the world happen around us. But from the characters stand point with differences value and backgrounds, they cannot and will never approach things with the same mindset like our own. The only thing important is how they feel and act relative to their world, everything outside of that is meaningless.
