I like someone.
He is the emperor, but he pretends to be a knight.
He was so infatuated and dedicated that he waited ninety-nine years just for that young man who walked like water.
The young man is gone, and only the Ghost King remains.
Will you wait any longer?
I don't know where love comes from, but I am deeply in love.
Check your eyes, you are the right person.
I'm waiting for you.
PS: This book is BL, the emperor's knight (attack) x the dark ghost king (suffer)
