A Dragon's Gem: Yandere Prince Namjoon x Princess reader

What if you were a princess forced to love an evil, unforgiving prince by the name of Namjoon?

Namjoon meets you, a girl who feels worthless and scared. He makes you his princess and keeps him all to himself, killing anyone who even looks at you.

By the way, Namjoon will also be referred to as RM/Namjoon in this story. Please go easy on me, this is my first ever fanfic. And my ever first BTS fanfic at that. There's also some minor swearing, mentions of blood and killing, and Namjoon being possessive, so if you're not into that, then I suggest you don't read this. I would also appreciate kind, suggestive feedback from anyone who reads this.
