Severus Snape

You were in love with a professor, you are 15 years old
One day after class, when everyone had left and you were about to leave, you suddenly heard the voice of the provost professor.
—Miss Uzer, you will stay—
It was like a bolt of lightning went through you, you were never kept after class
—I heard rumors
—What rumors?
You thought, "What the hell are these rumors!? The ones about me being able to out-prank the twins, or the ones about me being in love with him!?" Neither one was good. If it was the first option, he's your dean and can make you scrub boilers, but if it was the second...

• Miss, don't act stupid, you understand perfectly well.
  —Professor, I really don’t understand what rumors you’re talking about.
  You understood everything, but what if you misunderstood and it’s still about twins?
• those rumors that you are in love with me
  You felt a jolt of electricity and suddenly, through the fabric, you felt that the diary with the portraits of Snape that you drew yourself was gone!
  The professor took your diary out of the desk drawer.
  -And this is confirmation, what are your excuses?
