"Continue this path… And you will see… You won't fear losing someone anymore," Rudeus said.
In his final moments, he realized something important, looking at Adam who cast away his fear to gain more power and surpassed his limits.
Adam walked toward Rudeus but then he stopped when Rudeus said these words as if he was giving him the time to speak.
"Fear to lose someone, huh…" Adam mumbled.
As Rudeus said, feeling fear was not always a bad thing, and more importantly, Adam would never be able to love someone if he didn't fear losing them.
After all, not even God could control people's feelings, so even if Adam became confident in everything he did, it didn't mean that the people he cared for wouldn't leave.
