Ghostly Obsession

William James Moriarty is a genius, a mastermind, a revolutionary... and now?

He's haunted.

Y/N was just a regular college student-until Truck-kun yeeted her into the afterlife. Now, she's a ghost, stuck in the 19th century, and guess what? She's living her best afterlife!

With no responsibilities, no exams, and unlimited time to fangirl, she does what any sane person would do-stalks William James Moriarty. Forever.

She whispers during his meetings. She messes with Moran. She steals Albert's books. And somehow, despite all her chaos, she makes William's life... fun?

Now, William is determined to uncover the truth behind his annoying (but weirdly endearing) ghostly companion. Who was she? How did she die? And most importantly-is there a way to shut her up?

A comedy-filled ghost story where one genius criminal mastermind gets haunted by his most unpredictable enemy yet-a fangirl.

Y/N: "...I know this sounds impossible, but... I was the cat. And before that... the ghost."

William: arches a brow, lips curving "So the lazy creature in my bed and the spirit haunting my halls were both you? I must say... you've been keeping yourself busy."

Y/N: "W-William!" flustered, covers her face "Don't say it like that-"

William: leans closer, voice silky
"Why not? You slept in my arms every night. And now you return as a woman... beautiful, warm, trembling in my sheets. How exactly am I supposed to behave?"

Y/N: blushing furiously
"...You're impossible."

William: soft chuckle, brushing his fingers along her jaw

"Perhaps. But you must admit... you chose the most interesting way to stay by my side."
