Classical Ancient Books and Ancient Members

In the Classics Department, Eru found an old book that had been carefully repaired. "I'm curious - who marked it in such elegant handwriting but never left a name?" She followed the lead and found out that it was a taciturn librarian who had been quietly repairing damaged books for many years without making any noise. Eru did not reveal it in public, but handed over a note: "The way you protect knowledge taught me how to cultivate myself." The other person raised his head and nodded slightly.
