Imagine being kin to your sworn enemy.

Killed in battle while defending his country, Bern wakes up in the body of the enemy prince, Kalian, and vows to avenge his people. But between taming an abusive half-brother and surviving his mother's deadly web of intrigue, sweet revenge seems to slip further beyond his grasp at every turn.

I could hear the hum of life in my ears. It was hard to breathe… I raised my gaze and stared into the distance. However, my blurred vision could not see anything. The light began to fade. That was my last memory.

When I opened my eyes once again, it was ten years before that last memory took place. And of all the things I could have become, it was from the enemy country that drove Secretia to ruin – I had become Kyris' third prince, Calian.

…..

Bern was the proud Crown Prince of Secretia who fought and died in the war against Kyris. But he woke up ten years into the past – as the timid Third Prince of Kyris, Calian.
