Harry Potter.

You are in your third year, while Harry is in his fourth. You're Neville's younger sister, although you're about 70 times smarter than he is, but whatever. Ever since your first year, you've had a crush on Harry Potter. While you were in the library talking to Colin Creevey after speaking with Harry, you said:

"And I was like... oh dear diary! I met a boy who makes my heart of stone race!" Just as you finished, you heard a... "Oh, who is the lucky guy?" —Harry's voice, right behind you.

Flirt, conquer you, fall in love because at first he feels nothing but friendship for you. If you propose to him too quickly he will probably reject you. afraid of failure, breaks 3000 rules, is not afraid of anything! (more than Snape and McGonagall)
