Monarch of Evernight - Volume 1 - Chapter 21: The Definition of Genius

Villain System: Activated> Alignment: Chaotic EvilObjective: Obey the plot, serve the empire, die like a good villain.Yeah, no thanks.I woke up as Dorian Valen—sadistic noble, arsonist, war criminal, mid-tier villain with a face everyone wants to stab. The story wants me to beg for my life, cough up secrets, and die at sunrise so the hero can get a shiny new power-up. Been there, read that.But I'm not here to follow the script. I'm here to flip the table.I’ll expose the cracks in the empire, dismantle the hero’s halo, weaponize every trope, and corrupt the system that tried to cage me. And if I have to burn the world down to do it?Well… I’ve got the villain system. Might as well make it earn its name.

My lover has always been a little pitiful, but he will eventually turn into a big BOSS;

My lover has always been in love with me at first sight, but I also think he is very pleasing to the eye.

My lover has always been jealous, but I didn’t know what he’s jealous of. It is really troubling.

My lover has always had two faces; the face he shows others and the one he shows me which are completely different. It’s very confusing…

Bai Duan: This is my life. ╮(╯▽╰)╭
