In the mystical land of Dragonnia, Kademon, the last successor of the powerful Rainhart dragon lineage, enters a marriage with Raya to repay a debt owed by their families. Though Raya despises her husband and secretly longs for another man, Kademon quietly uses his immense power and influence to protect her loved ones from danger. Without seeking recognition or affection, he remains devoted to his promise until the day his obligation is finally fulfilled. Choosing to leave rather than endure a loveless marriage, Kademon withdraws his protection, and Raya’s family soon faces ruin. Only after losing the man she never truly appreciated does Raya realize the sacrifices he made for her. Left alone with the consequences of her choices, she must confront the painful truth that her greatest loss was the husband she never understood.
