Behind a mask

Who are you?

It's a next school day and I'm the completly opposite of motivated.. like always.
The same people, the same location, the same time, the same weather, the same uniform.. it's always the same. I'm walking through the hallway and suddenly some guys stop me.
"Hey.. get out of my way."
I say and try to pass them but one of them graps my arm so that I can't escape.
"Let go of me!"
"Hey hey. Not so fast. I just want you to do my homework."
"Why would I ?!"
"Well I heard you're pretty good so why not?"
I'm annoyed and release my hand out of his grip. I go into the class and
feel like someone is pulling me back.
It's one of the boys again.
"Didn't you hear him? He said that you should make his homework."
He says.
"Well too bad.. i don't want to make his homework. And now let go of me."
"Well too bad.. i don't want to let go of you."
I roll my eyes.
Right after that the boy grabs my collar.
"Wanna die?!"
He raises his hand ready to hit me. I close my eyes exspecting the pain. But.. i don't feel anything. Surprised I open my eyes and see another boy holding the hand that was about to hit me.
"Leave him alone you fools."
My collar is released and I take a few stabs back.
The boy that just saved me agues now with these idiots.
"Oh playing the hero or what?"
"Yeah yeah just piss off."
Then finally the teacher comes and they stop arguing and go to their seats.
After school i try to speak to the boy to thank him.
"Hey you."
I call after him.
He first can't hear me but after I shouted a second time he finally turns around.
I look up to his face and..
"Wow.. you're really handsome."
...
...
Shit.. did I really just say that?
"Oh uhm.. thanks? I think?"
Wow Mizuki you just managed to embarrass yourself head over heels.
Ok calm thyself. Just say thank you.
"Yank thou."
THANKS FOR NOTHING TONGUE
Ugh why am I so nervous? Why does my heart beet so fast? Why do I feel how my face turns red? Why is he so good looking?
"Your welcome."
His calming voice brings me out of my thoughts.
His smile is just magical.
He turns around again and goes away.
That's the first time that someone can completely disassemble me only by looking at me.
"Who are you?"
