In an alternate universe where South Korea is a kingdom split into dystopian islands, a caring man from the slums embarks on a refreshing adventure after being picked up by a pirate crew aboard a ship called The Wonderland. Romance, family, friendship, vengeance, and a battle of morals make waves in this troubled archipelago. ◇Book 1◇

Seonghwa has fully accepted his role as the "Pirate King's lover" and his new lifestyle aboard The Wonderland. Yunho and Mingi are finally together. However, a new label has been given to their conflict with the Tyrant Queen: war. While taking on this final struggle for the future of the South Korean archipelago, Seonghwa and Hongjoong have each other for support, but will it be enough for the battles ahead? Can Mingi overcome his trauma to protect Yunho from the tragic fate he's foreseen? ◈ Sequel to Treasure, Book 2 ◈

Jeong Yunho grew up with hardly any emotions. If he had no toy to play with, he stared at the wall. If he was told to kill someone, he did it without a thought. Song Mingi was known as the dumb prince who couldn't keep up with his brothers. Then one day, he suddenly no longer had competition. Instead, he was taking the torture for all three of them. A soldier with no mind for himself. A prince with no hope for life. Until they snap. Like a change in the tides, they begin to desire more. ◆ Prequel to Treasure, Book 3 ◆
