                                                Lux and Adrian are the same person. Carlo is going to come back based on early chapters. Besides NOVEL SPOILER (though I only read 40 chapters) Adrian saw a white haired guy in his  dreams, and he assumed this person is Carlo, which is why he chose to stay close to him. However, we know Adrian actually saw Mikhail but so far he did not realize it wasn't Carlo. 
Anyway he is important and it gives us Adrian's backstory as well                                            

 
		
i can’t get it why we’re also delving with the past white haired guy in lux’s life.. why not just focus w white haired guy during adrian’s?
