Original Webtoon

Yugo and Karen, a brother and sister with pale blue hair, live quietly in the countryside of the Stella continent, where four countries compete for territory, wealth, and even human rights and lives. One day, Karen is kidnapped by bandits wearing crow masks, and Yugo, who is left behind, is also captured as a slave. The resourceful Yugo is not sold and is kept as a servant at the slave trader Seacock's mansion, but his role is as a ``pet'' for the mansion's beautiful only daughter, Layla.
