Think about it. Each book is an album. And it's a vault. So multiple shelves. So many images per person and he knew all their names. So he knew them personally, and they probably knew him personally as well. What a betrayal and violation. An album full means repeated rape too. Extended trauma to his victims.
And gyeongdo knew what was in the vault. So he probably bragged about his "collection" to him.

YALL THAT OLD CUNT HAD A WHOLE SHELF FULL OF PEOPLE LIKE THIS THE EPSTEIN ISLAND OR SOME SHIT
