I think Teahyuk js currently "travelling" in Hyo-un's memories after his death. Touching Hyo-un could potentially make him apears as a person in his memories and not a "ghost" watching from a far. In my opinion orb contains all memories from the past not only the one's that Taehyuk had to make sure he remembered everything from his past lifes
I'm confused can someone explain it to me how is the past Hyo-un ablle to see present Teahyuk isn't this whole thing just and illusion to Teahyuk to help him get his memories back
