@bonergore I may be a little late for this but…
How about that Pico and the reader are both working as hitman and they unexpectedly meet trying to take eachother down but end up starting something new
It’s just a suggestion
You could probably do some interesting stuff with the idea of having a Y/N who may not be totally cool with the murder thing. Would he try and hide it? If not, for how long does that work? What stuff does he not tell them?
