Comments of chapter undefined of Obtaining 10x rewards! Reincarnated into a novel as a side-character!

Oliver was known by many servants to be a worthless, talentless but a smart child many of the servants. Also, Oliver was able to quickly find where Nadia was training so the whole clan area must be small. Although Oliver was a child that had been kept hidden for over 5 years, Nadia should atleast have some clue about him. Also, there should be some explanation as to why Oliver was kept hidden for 5 years not the nonsense "He was trash so no one should see him to not tarnish the family" reason.
