"He wants my blood, and I want his life!"
In order to undo the cursed blood, I mistakenly entered the underground palace and awakened the ancestor of the blood clan who had been sleeping for thousands of years.
He regards me as something in the palm of his hand, imprisoning me in eternal night, demanding my blood day and night, thinking that I am his only "antidote".
But he doesn't know that I, a genius pharmacist, have already tempered every drop of blood into the most deadly poison in the world.
He hunts my blood, I hunt his life.
In this top-notch game in the name of love, in the end, who will become whose prisoner first and who will perish together with whom!
"Eternal Night Prisoner", witness an extremely crazy love and murder!
