The Student and The Librarian

"Back again so soon? Most students would have finished those books in a month."

You didn't expect to see him here that fast. Perhaps he is a fast learner.

"I am a fast learner." 

"We didn't introduce ourselves the other day. Maybe because someone decided to sneak up on me." You teased him. 

"Apologies, but you were so focused on your job that I had to startle you. Kaecilius."

"Apology accepted. (Y/N)." 

Atleast he had a sense of humor. Some of the people were like a rock and don't respond to jokes.

"I recommend reading these, since you finished those." You hand him a stack of books.

"Thank you." Kaecilius takes the books you have given him and left. 

You don't know why, but you want to see him again.
