Immune

I'm betting on it, that college girl and Seon-woo is probably immune. The one theory about the blood being exposed to the air and making it less infective is probably false, and the college girl who supposedly ate food with that pink haired bastard hasn't shown signs of any symptoms except her scratching, but it's because of her eczema, so in short, they're probably immune. And imma guess that when they realized she had ate the same food as the pink haired creep they probably would try to kick her out, especially with that tyrant doo -doo yuhk idk the spelling of his name but he pisses me off, anyway, then beloved Oreum probably will cut in and say it's been days and all and she hasn't shown signs of turning.
