This person is very hot and seggc. Killian is mostly known for their aggressive and playful personality. Most people find them annoying and manipulative but if you get to know a Killian, you'll find that they're actually not that bad! (Even if they pretend to be). Killian is also known to be a liar but they can't really control it because it comes naturally to them.
