A/N: I just thought about this fic, and for a change, it's all about Gryffindor Quidditch chaser Katie Bell. Hope you'll like this. The setting is during 3rd year at Hogwarts.

Katie's Diary

Summary: Katie Bell writes about her unusual crush on her secret diary (You'll be surprised to find out who it is!).

Chapter 1-Secret Crush

Dear Paige,

It's been a long and tiring day today, and I have to get some sleep. But I won't be able to without writing to you first.

I had Quidditch practice the whole afternoon, and it went well. And did tons of assignments- wrote two parchments of an essay for History of Magic, wrote my predictions for next month on Divination, researched on exotic medicinal plants for Herbology, and another research on Potions.

Speaking of Potions, we'll be having it by tomorrow…

Katie Bell paused from writing and sighed heavily. She couldn't understand herself why she was so eager to see him during that period. She had been acting this way since last month.

I can't wait to see him again. I don't know what I saw in him, and I can't explain to myself why I like him so much, even though he's mean and nasty, and his hair is greasy (NOT matinee idol material). Of all the guys in Hogwarts, why do I fancy him?

I feel so embarrassed for myself. I can't let anybody find out about this, or else they'll laugh at me. I wish I can let go of this easily, but every time I see him walking down the hallways, in front of the class, or at the faculty's dinning table come mealtime, I secretly swoon for him. I feel glad because of this, that I actually liked a guy this way. It would have been better if he was my age, or if he was somebody else. But he's not.

This is so complicated, that I don't want to think about this anymore. I hate myself that I always think about him. Of all people, why do I have to fall for the Potions master? What did I saw in Snape that I didn't see in any other guy here?

Won't he ever teach us how to make an anti-love potion?

-Katie

She closed her diary, clutching it tightly in her hands. She just couldn't believe herself that she was writing about Snape, the hated Potions professor. Katie shuddered at the thought. She wanted to get rid of her affection for him, but the more she tried to, the more she ended up infatuating on him.

If only someone can advice her about this, on how to deal with it. But she couldn't simply tell a soul about it, even to her closest friend, for fear of being laughed at. She could only imagine the mockery she might have to endure should her classmates know about it. So might as well keep it to herself, and act unaffected around him.

Katie hid the diary under her pillow, and made sure that no one in her room could see it. She looked at her roommates, who were soundly asleep. Thankfully, no one had seen her writing in her diary. She always made sure that she'll only write in it when everyone is asleep, or during daytime, when no one is in their bedroom.

She lay down on her bed and tried to fall asleep. But all she could think about were the things she had written in her diary. She thought, he's a guy and I'm a girl. There's nothing wrong if I'm crushing on him. But why did it felt so wrong? She was disgusted at herself for liking him.

A/N: I used to do this too… hehe. ;) I also had a crush on one of my teachers back in high school (but that's another story), and that inspired me to write this. This fic is dedicated to all who ever had a crush on their teachers, good-looking or otherwise.

Thanks for reading! Reviews please! Up next is Chapter 2!
