Nah I think they forgot or they were just trying to move the plot along and didn’t have time, anyways I’ll be here if novel reader comes by
Uh what biological son?
It's this orphaned kid with a very powerful relic. MC was gunna use him but since there a law that's says kids can't hold relic without parental supervision, he used Jaeha to be his fake father. But it was later found out that they were biologically related. After a few chapters they completely erased him lol im pretty sure he was also helping jaeha restore relics too
Oh yeah forgot about him. He just disappeared
This is getting intresting.... but they forgot to clean up the biological son stuff ...or did I just miss that part?!
