the start of story

I will remember that day forever  in 2000 when i received a letter from xx.To be  frank ,i never noticed him before who sat behind the classroom .in my mind ,he was a bad boy.maybe you can guess what the letter read,yes,i love you .what a surprise.however,I was a hard-working student that time with a strict behavior.though i denied him .he said he would wait for me.But since that day,i started to notice that boy.i found he is really tall with a handsome face.he looks cute when smiling,he likes to help others .most important,he began to study rather than hang out with his fellowers.in a word ,finally i found he was not a bad boy.maybe what he did was just to please me,anyway i fell in love  with  him after 2 weeks .....i prepared to write back to him ,but i  did a  stupid thing .
