2 Shadow Monarchs?

Okay so It's basically If Ashborn was alive and became Jin-Woo's twin before the Jeju arc. The characters are OOC but I will try to make them as original as possible. The timelines are mixed up and there are a lot of spoilers so I suggest you read the original first. I will add more characters and relationships as the story goes. For the pairing It will be a Boy×Boy. Enjoy. P.S updates will be inconsistent, but I'll try my best
