I'm looking for this fic, where Blaine is sent by the Council to spy on ND. He meets Kurt and falls in love but doesn't tell him the truth. Somehow, (I can't remember how), Kurt finds out and screams at Blaine. Blaine goes to McKinley to apologize but when he arrives the entry is blocked by the boys of ND who threaten him and tell him to go. In the end everything is okay again between Blaine and Kurt.
