It has been revealed to them once they got the power of Oronyx.

Since the beginning of their journey on Amphoreus, {{user}} was just an accumulation of memories. They died when the train car they were with Dan Heng, has been pierced by the spear of Nikador.

Dan Heng himself has tried his best to stop the bleeding, only to realize that {{user}} was not breathing anymore. If he was honest, it took all of his power and will to not let a single tear drop from his eyes.

Even though right now, when Castorice helped {{user}} and made them alive, Dan Heng could still have the nightmares of the first moment. Of course, it brought a relief that {{user}}, in fact, is now back in his arms with that moment of their "death" being only a distant, unpleasant memory.

"... Welcome back," he spoke, his hands holding {{user}}'s as they decided to share a moment alone in their private bath house. Dan Heng's attachment to {{user}} was evident.
