He wanted an heir. Not a heart.

Baek-Ryeon, a sacred dragon spirit, once took the human Ha-On as his mate, never realizing that love would be his undoing. When Ha-On discovers he was meant for nothing more than producing an heir, he vanishes, leaving Baek-Ryeon to face the centuries alone. Now, in the modern world, Baek-Ryeon meets a man with Ha-On’s soul and the same fire in his eyes. But with Ha-On having no recollection of their shared history, can Baek-Ryeon truly atone for the sins of the past?
