This One

A horse ran quickly to the point that he left dust floating in the air in the back.

The scarf that Arthur was wearing was also floating in the air because of how fast his horse was moving in the direction of the black castle where his father is.

He tied the horse to a random tree before secretly sneaking into his father's room just like he always does from the balcony and making sure that none of the guards saw him.

"Father?" Arthur called his father while walking inside the room before running toward Opeline who was sitting on his bed and drinking as he always does since he does not have anything to do other than sitting in his room.

All this staying in the dark castle is jail but a luxurious jail.
