Gallerian and Michelle
I think Gallerians and Michelle's relationship isn't as good as people make it out to be. I do get it, I love when there's a sweet father-daughter duo. Gallerian is for sure a loving father. But he isn't a good father. There are some unhealthy aspects to it.
First of, I think him refusing a divorce makes him immediately a bad father. It's so classic, parents saying they'll stay together for their child's sake, when that is the most harmful thing for everyone involved. I think it's clear the troubled marriage is affecting Michelle very negatively and Gallerian is the most at fault for that.
Then I think there's a very overlooked misogyny in their relationship. I think Gallerian babies her a lot. I mean, I mistook Michelle to be 12 when I got into Evillious. I think the people around her treat her to be younger than a 16 year old, especially Gallerian. I've seen an interesting comment from someone once, "people treat Michelle as a child and Margarita as an adult despite them being the same age" (this topic definitely deserved exploration too). Michelle is so babied overall. And that's not so strange, she barely has screen time. We mostly see her from Gallerians perspective. This innocent perfect angel for him to protect. How he treats the doll shows that.
I do want to point out that Gallerian is mentally unstable post contract, and that would change his behavior. I do not think he treats Michelle exactly the same way he treats the doll. But I do think how he treats the doll reflects how he sees Michelle. The disability adds onto how he babies her. I need to save her! I need to heal her disability! She can't do anything without me! I see their dynamic as a paradox.
Irina/Maria has always seen herself/been treated as a doll - and Gallerian is one of the only she feels is treating her as a human. And he does view her as a human, despite her being a doll. But at the same time, he does treat her as a doll. His miniature garden girl, who he can decorate a dollhouse for.
Then at last, this "devil" vs "angel" mentality Gallerian has about himself and her. He's this big bad man who's tainting this little angel of his. He isolates the doll to shield her from the outside world. He doesn't want her to know how deranged he is. He wants her to be forever happy in that world of rainbows and sunshine. And maybe, that's his way of clinging onto the thought of not being all the way rotten. Him being a loving father seems to be one of his redeemable qualities, when in actuality I think it's the root of the problem.
I don't think it's as unhealthy before Michelle died. But still, far from perfect as many want it to be. Father's babying their daughters is such an overlooked aspect of misogyny. I don't think it's all that cute, honestly.
