Game of hearts

This three kingdoms have been at war for centuries. Each kingdom has an heir. Two of the heirs didn't stand eachother. One of them was: Kim Taehyung, son of king Kim Namjoon. He was named the son of mermaids because he was as handsome as one, the cruel prince. He was named like this because he killed every man with no mercy. He is the prince of the Golden kingdom. The second heir was: Jeon Jungkook, son of Jung Hyun. He was named the son of fire, he was named like this because he was born in the biggest fire his kingdom has ever seen, Flame of bravery because every time he showed his bravery to his people he looked like he had flames in his eyes. He is the price of the Fire kingdom.

But of course there needs to be a third prince right. This prince was not cruel,no fire in his eyes. But beauty. The most beautiful prince that eyes of men had seen. He was named son of god,because people thought only gods had so much beauty. He was named the Frozen Rose ,because no one knew how such a flower bloomed in the cold. His name is Park Jimin. He is the prince of the Ice kingdom.
