By Crown and By Heart ( Soukoku )

Prince Dazai was never one to follow the rules. When he caught a fiery-haired thief sneaking through the palace grounds, he didn't call for the guards - instead, he made a request. He wanted to see the world beyond the golden gates, away from the weight of royal duties. And Chuuya, reluctant but bound by the prince's stubborn charm, became his guide.
What began as a reckless adventure quickly unravelled into something more.
From the bustling streets of the commoners to the dark corners of the underworld, Dazai and Chuuya faced treacherous schemes, tangled alliances, and a looming engagement that threatened to cage Dazai forever. With assassination attempts and whispers of rebellion rising, the prince's carefree facade cracked - but so did Chuuya's carefully guarded heart.
