Crown Meant for Two Hearts

In the tranquil Lee Kingdom, Crown Prince Heeseung is a symbol of quiet strength and tender warmth. A lover of art, poetry, and peace, Heeseung’s heart was promised to Kim Sunwoo, the fierce war general and Crown Prince of the powerful Kim Kingdom. Though their paths crossed only once in their youth, that fleeting encounter left behind a fire that grew into love through years of heartfelt letters.

Sunwoo's letters were painted with tales of victory and valor — each one soaked in dust and blood, yet always ending with longing. Heeseung’s replies were filled with dreams of a future home, shared mornings, and a gentle world far from the battlefield. Their love blossomed in ink, steady and strong.

Until the letters stopped.

Weeks passed. Then months.

Heeseung was left alone with silence — no words, no closure, only a growing ache that twisted into heartbreak. Forgotten. Abandoned. His once-bright eyes dimmed, but his love never faltered.

Then one morning, everything changed. The palace guards bowed and declared the arrival of his long-awaited fiancé: Kim Sunwoo.

Heeseung ran to the courtyard, his heart soaring. And there he was — the same familiar eyes, the same face. Heeseung threw himself into his arms, whispering his name like a prayer.

But the man before him was not Sunwoo.

It was Kim Sunoo, Sunwoo’s younger brother.

Sunwoo had died in battle months ago — but with his dying breath, he begged Sunoo to protect Heeseung, to keep his heart safe, to fulfill the promise that love would still reach him. So Sunoo came — wearing his brother’s name and title, prepared to bury himself in duty.

Heeseung, unaware, gave his entire heart without hesitation. He loved with devotion, vulnerability, and passion — whispering dreams into Sunoo’s ears, kissing him under moonlight, and planning a lifetime together.

And Sunoo — torn between guilt and the undeniable warmth growing in his chest — began to fall.

Heeseung's love, so pure and consuming, became Sunoo’s greatest torment. Every touch, every kiss, every whispered “I love you” was meant for a man who no longer existed. Yet Sunoo, against every vow he had made to himself, began craving those words for himself.

Caught in a cruel war of conscience, Sunoo lived each day as a thief of another man's love, while Heeseung loved him more deeply than ever — completely unaware that the man he held was not the one he was promised.

A tragic, tender love story of one prince loving blindly, and another loving in silence — caught between duty, deception, and the haunting possibility of a love that was never his to claim… yet now feels like it was always meant to be.
