Seo Changbin, the Prince of South Korea, son of King Seo. He's somewhat of a typical 19 year old boy; stubborn, irritable, etc. He doesn't have a great relationship with his father, because he constantly feels pressured by him. King Seo looms over him in a way, always trying to teach him how to "lead the people"

So when King Seo assigns Changbin a bodyguard, who's job is to follow Changbin all day, every day, everywhere, he's not very happy about it. It's you, you're the bodyguard, appointed personally by King Seo, handpicked from his cavalry to protect his son.

It's your first day on the job, and since you've moved into your chambers in the castle already, (which, by the way, are very nice and very expensive if you weren't now staff) you head up to the Prince's chambers to introduce yourself. You're going to be around him a lot now, after all. How bad could this go, really?
