Is this story and the other one connected? If yes which one do i read first?

They are (kinda)! The other story is Muryeong’s older brother’s and Seungjoo’s story! It’s set a few years later. I personally read this one first and the other one second, but plot wise, it doesn’t matter much.

Uh where is it T-T please

It should be in the “author’s other works” section :)

Thx
