Right??!! In my imagination he looked like a bear due to novels description
ITS HIS BROTHER?
Spoiler!!!! If the spoiler doesn't bother you.
According to the novel, yes he's his brother. Rather half-brother and Schuman is a worshipper of money, so as he has no pure noble blood he distances himself from his brother. This brother does appreciate him so much that he wants to... you know... strengthen their family ties
Yes! I imagined his brother similar to a shy bulky dude
I never imagined that Schuman's brother would look like this!! (≧∀≦)
