NamGungMun (남궁문)

He wanted an heir. Not a heart. Baekryeon, 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 Baekryeon to face the centuries alone. Now, in the modern world, Baekryeon 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 Baekryeon truly atone for the sins of the past? (Source: Lezhin US)
