Gu Xingchen enters an infinite-instance dungeon and is immediately pursued by the husband he had in his previous life. That man is aloof and obsessive, and every time Gu Xingchen is on the brink of death, he breaks through the deadly trap to save him. It isn't until one instance collapses that Gu Xingchen finally sees the ghost's true face: Wei Luochuan, the ultimate boss who controls every instance.
“Xingchen, stop running.” The man grips him around the waist, his eyes wild with the madness of having regained what he lost. “I was wrong back then. In this life, you can only be mine.”
From then on, the instance boss becomes his personal bodyguard, following him like a ghost and spoiling him to no end. My Xingchen was always meant to belong to me alone.
