Luca and Axel from Holostars are just the densest MFers ever. They both had girls practically throwing themselves at them and they either didn't realize that was a thing, or just ignored the situation. There's a really great video of Axel annoying the hell out of RPR and Vesper with his main character syndrome, "Axel's harem protagonist stories with salty rpr and unhinged Vesper" by Khaos Clips, well worth a watch.
