(I'm begging you to) keep on haunting me (слэш)

“I don’t know why I keep coming back here,” Merlin murmurs, the words so quiet that Arthur almost misses them. “I know you’re not here, but—”
“I am,” Arthur says, knowing how pointless it is. “I am, but you should stop coming all the same. You should stop grieving me, Merlin, it’s not worth—”
“Sometimes, it almost feels as if you were. Here, I mean. Listening to me—but then, that’s a terrifying prospect because I’ve said a lot of things I didn’t mean for you to hear.”
You could tell me anything, Arthur thinks, his chest aching. You could curse my name a hundred times, and I would still want to see you.
