Just a question!! What does Galacta knight see in Sir Arthur??
your jokingly disgusted tone makes me believe you speak of the horrors i have created. i admire your attitude.
in the gameverse story this was admittedly not very thought out and i think mostly i just wanted them to be "friends" because it felt like a natural conclusion to whatever arthur had going on– he's finally getting over himself by forming a healthy relationship with someone he'd previously conditioned himself to hate, thus ending the "i'm always right and everyone i don't like deserves to die" mentality he had going on.
galacta has no real reason to like him though– the only reason he's helping arthur is out of the goodness of his heart, which actually... isn't super "healthy" for him right now? he just ended a previous relationship in the most disastrous way possible, and considering how destructive he is himself, he isn't exactly an ideal candidate for the "person who fixes arthur" position.
recently, i think i've gravitated toward a different direction where the relationship comes as a result of galacta seeing a lot of elements of his former life and ideals in him (including all that bitterness and self-righteousness) and deciding that it's his personal duty to make sure he repays the favor arthur did for him by being at least a little nice to him– he feels bad for him after all. i don't think i need to go too in-depth on how gala is endeared to his slow improvement and fascination with galacta's life and magic. and over time, this "unhealthy" relationship turns into something mutually satisfying.
the animeverse story on the other hand. this is the one i've been fixated on recently. and you can tell.
even though i've always had an answer to your question, in a previous post i stated that the reasoning behind galacta's "feelings" didn't matter, and i think i've changed my mind a little but not completely (this sounds like a cop-out lol)? at it's core, it's like this: galacta sticks with arthur out of convenience because of how much better he is at the pr stuff, but just can't get rid of him because he's afraid of what arthur will do– and worse, he's [drumroll please] grown attached. because he's really, really desperate.
he's been alone for so long and struggling to keep himself stable. arthur is drawn to galacta because he's hot and powerful and has taken him to great places, and galacta is drawn to him because he needs this, and arthur is essentially his only option because of the situation he's put himself in. i haven't talked much about what arthur is like without galacta, but it's just about as bad as what he's like without gwen. they're in this very strange spot where they essentially just make each other worse and worse for the sake of the narrative.
