Aurora

2 boys, 2 different lives. San and Yunho are cousins who lived very difficult lives. San and Yunho grew up on the streets, unaware of what they really are to the mainland. They found comfort in one another and worked to keep them both safe. One day while they're working to get money and food (both working at a tavern), a group of pirates come in, loud and obnoxious but filled with some feeling that San and Yunho couldn't put a finger to. They stay late as usual to people who want to get drunk and all, and when San and Yunho attempt to head home after they finished working and got their money from tips, something occurs.

And suddenly San and Yunho are thrown into the pirate life as "guests" (more like prisoners) of the pirate group, Ateez. They're onboard the ship, Aurora, and from there they learn what they are, and why their lives are this way.
