Two Fics
Hey everyone! I'm looking for a fic I read a long time ago. I don't remember the name, but in it, Harry becomes friends with Draco and the Slytherins, and all his friends turn against him. Basically, at the end, he's about to sleep with Severus and the whole of Hogwarts is watching through a transparent wall, laughing at him, and he leaves Hogwarts. In the sequel, it's revealed that it was all a plot to keep him safe.
In the other one I'm looking for, Harry and Severus are fighting (I don't remember why) and Harry enters into a relationship with Lucius and lives with him. I remember that Lucius has a room with a ton of snake portraits in it, and he has a major Parseltongue fetish. Harry and Severus do end up together eventually.
