Mujin died just like that, real quick, and got bound to a System.
Mujin spent hundreds of years winning over male leads. The first time she fell for someone, though, it turned out he wasn't simple at all: a sweet, innocent fool in one world and a wolf in sheep's clothing in another. She saw through every trick, every single one.
She took the chance to hack the fussy old System that kept getting in her way. Wouldn't it be great to have a little underling System instead?
In the end, she discovered that she was actually the God of the Mainframe's...
That God of the Mainframe played dirty, tricking and ambushing a teenager like her. She advised him to quit while he was ahead.
Otherwise, how about a little time in the dungeon, a cage, and some chains?
One-on-one.
The male lead is the God of the Mainframe, and there's something a little wrong with his head.
The female lead is sweet on the surface, ruthless underneath.
Any professional details are just me talking nonsense.
