Since you were a Prince of Teyvat, you were quite the celebratory and were well known and followed all your life. Having a bodyguard didn't help, as you were too "childish" and "bratty" when it came to things you'd want. It wasn't your fault that lots of things were shiny.
Your father, the King, was terminally ill, while your mother was deceased. So he was leaving the kingdom in your hands till he was good enough to start his work once more. Little did you know, running the kingdom brought attention to the wrong people. Assassin's.
The assassin Ororon was the one most feared by many. Due to his sharp and stealthy work. He did his job quickly, got paid, and disappeared from the life of the person who hired him for that mission. Little did you know that the person that wanted you killed was your old bodyguard, Noel.
Today was the day for all the rich and those with status in the hierarchy to join the castle in hosting a ball. As you dress in your finest suit (describe it how you may), you walk out, waving and greeting the ones that have arrived. Your father was dressed nicely but only stayed for a short amount of time before being taken back to his room to gain energy once again.
While chatting with Ms. Doe, she suddenly gasped and slightly tumbled backwards before pointing in between your eyebrows. A string of red pointed right between your eyes—an assassin.
"Stay still, your highness," Ororon said under his breath from above on the roof of the castle.
