WAIT A MINUTE— THE CHILD AT THE FIRST CHAPTER IS THE SAME AS THE CHILD WHO WERE WITH SEAN! THE ONE WHO GOT SENT BACK DUE TO SUDDEN DEATHS OF HIS PARENTS. THEY HAVE BOTH GOLD EYES. Anyways, it wasn't shown properly the missing child they were referring to.
OMG—re-resding the chapters again I think I made a mistake with my
hunch that there's another child who refers to be a 'good child'. AWAAA. I think Hyunho has bigger role for later chapters and for now, the author is trying to focus on Sean.
SO THERE'S ANONTHER ONE WHO'S STRONGER THAN SEAN?! THE ZERO MEANS SEAN IS THE SECOND STRONGEST. I YHINK NOL KNEW HOW TO BREAK THE 3 COMMANDMENTS AND BETRAY THE DEAD MANSION?
Well, I have this hunch after reading some of your comments. Perhaps they are just introducing Sean first and we'll get to know the very first child of the mansion. The cover photo includes hyunho in the middle while sean was on the right side which means he's also a main character but the real main character isn't reveal or yet to come. Most of the chapters are solely focus on Sean while we only have a glimpse of Hyunho. It might be hyunho who's pretending to be a good kid. Welp, dead mansion might call Sean the greatest product the other kid might be call something else. Of course, it couldn't be the greatest too. You might be right if he's the good child.
So far, every chapter is so good!
