I honestly cannot thank you enough for the bpd Lucio post. I'm borderline as well and struggle pretty hard even with being medicated. So to see someone share the idea of Lucio having it is very validating and rather heart warming. I think that's also why I sympathize and gravitate towards him so much.
I feel you; it’s a headcanon I’m really attached to, especially the more we see of his route being about starting a positive cycle, rather than “fixing” him. The fact that all of Lucio’s Very Neurodivergent Behaviors are treated as character traits (and sometimes, things the MC likes about him) instead of something inherently wrong with him or something that needs to be stomped out makes me feel a lot better about my own VNBs, and I think that’s why I like digging into him so much, too ☕
