You currently live in the richest kingdom. Well, a few days ago the king has died and Prince Taehyung hired you, the best knight of the kingdom, to protect his sister, Princess Sana. So, you were heading to the castle when you saw a kitty jumping on you and you see the princess running to the cat.

"I'm sorry! He escaped from my room!"

She said, taking the kitten from above you. It's strange, Sana seems like a sweet person now, but she was always arrogant, maybe it's because of the cat.
