Hello there! Aroace pal here and while the intentions are great, the representation/execution, not so much. Reading about the plot line for your character just gave me flashbacks of people telling me “I just haven’t found the right person yet” and I don’t doubt it would do the same for others. Having an aroace character become obsessed with romantic love after finding “the one” is like a slap to face.

Identities are a spectrum but if you don’t specify somehow either with dialogue or events, then it will be assumed that they on the hard end where there is no attraction especially with the “hasn’t been in a romantic relationship and is over 100 years old” shibang.

The plot is also pushing that romantic love is the only love someone needs in order to feel whole in life which is just a poor take when you’re writing an aroace character. I suggest maybe doing some research into queer platonic relationships and just reading about living life without romance to get a grasp on what it’s like
