Finishing School, but Starting Life

Sasuke is a graduate student at Konoha University and is on his final year for his masters. One of the requirements for getting his masters is teaching a couple of labs at the university. On the first semester of his last year he realizes that something is different this year. A particular student stands out of the crowd and challenges Sasuke on everything he does. This student is starting to drive Sasuke crazy in more ways than one. What will he do about it?
This will be a PG-13 story for now. Will probably be mature later on. Sasunaru or Narusasu fanfic.
