Hear me out: Lawlight romantic fantasy AU
I think I've read too much villainess/isekai manhwa slop and it's rotting my brain 😭 This concept would suit Light trust me. He dies and is reborn as a villainess in a classic romantic fantasy setting, in the body of a noblewoman who is trying to steal someone else's fiancé or something (+1 Cliché point)
It turns out this world also has Death Notes. The original owner of the body tried to use the Death Note to kill off minor characters for her own benefit, hoping to gain the attention of her crush (+2 Cliché point). But when Light possesses her body, he uses this opportunity to try and become a god once again.
Buuuut L is in this world too. He's a Duke of the North (lmaooo) who does detective work as a hobby and is hunting down a serial killer. The victims keep dying mysteriously from unexplained heart attacks from before. And somehow most of these deaths directly benefited this noblewoman, who has suddenly started acting very strangely lately (since Light took over).
Now, Light has to clean up the mess the original body made and prevent L from suspecting him, all while continuing to act as Kira. Could someone please draw a manhwa like this?
