Looking for a specific fic, genius merlin

Hi~

I am looking for a specific Merlin/Arthur fic. I googled it with various keywords that I could think of, but cannot find it.

This fic describes genius Merlin's young life, like his going to and graduating from schools early, and then Merlin becomes a professor at the Camelot University in his early 20s, I think. At the university, Merlin met Arthur and Arthur first thought Merlin was a fellow student, but it turned out Merlin was his professor. Uther was the dean or something like that in the university.

I'd really like to read this again.
Thanks in advance.
