"Sleepless nights caused by terrors, defeated by one person." In the coastal kingdom of Wrmvil, Prince Luke struggles under the weight of his father's expectations and the burden of a dark secret: he plans to kill his father, King Charlie, and seize the throne for himself. But as his plans take shape, Luke finds himself drawn into a whirlwind of passion and deception that threatens to unravel everything he holds dear. When Luke meets Seven, Son of the biggest pirate captain, Luke sees an opportunity to manipulate his past lover, Elijah, and further his own ambitions. Using Seven as a pawn in his dangerous game of love, he intends to play with Elijah's feelings while keeping his own heart shielded from harm. However, as he delves deeper into his game, Luke finds himself confused by Seven's charm and finds his heart torn between duty and desire. Amidst political intrigues, adventures, and personal trials, Luke and Seven embark on a journey of self-discovery and redemption as tensions rise and loyalties are tested. In a world where the tides of fate can change in an instant, "A Restless Heart" is a tale of love, betrayal, and the power of actions, where the only certainty is that nothing is as it seems.
