Devil Falls in Love with Fairy (2023)

Two gripping tales intertwine in the shadow of malevolence. In the first, a tormented artist grapples with an otherworldly force, his creativity entwined with a demonic pact. As he ascends to fame, the sinister bargain exacts a toll on his sanity and those he holds dear. Simultaneously, a tenacious detective unravels a series of cryptic crimes, each linked to a devilish figure manipulating the strings of fate. Their parallel journeys converge in a climactic confrontation between good and evil, blurring the line between the infernal and the mortal. These narratives, bound by the enigmatic allure of the devil, spiral into a crescendo of darkness and redemption.

Both are mini dramas with a modern day FL who time travels or enters a fictional historical world. Both MLs are non-human (half demon vs. vampire) and bond in some way with the FL.

Both FLs are modern day people who enter a fictional historical VR world where they have to accomplish tasks. Both worlds involve demon hunting and ML is at least partially a demon.
