HELP on this certain BL novel I've read. Mystery and assassination/killer type? I remember one of the guys had blue hair. And it starts off with both of them attacking each other. The art is really good too.
Not any of these :/ his hair was more navy blue. The cover of Nevermore is pretty similar to it, but it was a different art style. Both main characters were also pretty crazy
Effs THE MAIN VILLAIN HERE WHO NEEDS TO GO IS TGE DAMN EMPEROR
