Crushing on My Best Friend

They met each other in Kindergarten. He kissed her on the first day of school.

Love at first sight you say?
Not really. Turns out he kissed every girl of the class on the first day.
Born player.

Girls either blushed or ran away except one who punched him in the face resulting in his swollen eye and her bruised knuckles.

So enemies at the first meet?
Nope. Lexi and Chris became best friends since then.

Chris grew up to be a player and captain of the school football team with a huge fan following of girls. He is unaware of the secret crush that his "best friend" has on him.
Lexi who is a tomboy prefers to keep this as a secret.
They are both 17 now, everything's going smooth until one day Chris receives a message from his secret admirer and he gets hell bent to find out who she is.

Who could this secret admirer be?

Let's find out!!!
