There's a lot of family drama involved but put simply,
a few days ago my half sister contacted me and I learned a lot about my brother since.
It turns out we are a lot alike.
We look similar, sound similar, we're both part of the queer community, he fosters guinea pigs and I have them as a pet, longer hair, both artists (im more of a digitalfurry one, ofc, but hes more of a traditional humanoid one), both the eldest sibling of our whole bloods, etc.
