OHH And one more plot idea

So basically the male lead is a sociopathic, psycopathic, serial killer. And not ur manhwa serial killer, like REAL SERIAL KILLER, (meaning he actually acts like one)

And then him and the FL fall in love and then he reveals his secret. This would usually be the part where the FL either fixes him or joins him, but here the FL would be like. “Oh… cool… I- Um.. I need to go to the bathroom)
Then she runs out the front door or whatever to the police station, he gets arrested, the FL becomes a detective, and that’s the end of the manhwa lmao.
