Sweet Blood Volume 2

"The taste of your blood will only change when you fall in love with me."

Kidnapped to a magical island, the greedy Sooho Lee strikes a dangerous bargain with the dragon-servant Ryuka.
Ryuka promises to pay Sooho valuable treasures every time the boy successfully feeds their vampire master.

He also must maintain the fragile deception that he's a girl.
But, the vampire already knows the truth.
The creature enjoys dark amusement by tormenting Sooho and luring the boy into his bed.

One day, a group of mysterious warriors arrive on the island and the young man realizes that his vampire master is actually a king.

And the fate of the world rests upon his blood.
