Reborn as the Enemy Prince Manhwa

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 10 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 became 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 10 years into the past – as the timid Third Prince of Kyris, Calian.
