It started with a pickup line

Liesel is a girl that has never been kissed and never felt the warm embrace of another person from another person other then her family and friends. But when Grayson comes in and sneaks a note into her locker for the approaching holiday of Valentines, what will Liesel do?
Will she get her first kiss? Will she agree to put her trust in him that this isn't a prank? That this isn't some meaningless dare? Will she experience her first heartbreak from the king of broken hearts or will they last?

His lips quirk upwards into a crooked smile, as if he can read my mind and know what I'm thinking. He pulls apart from me and I feel a pang of guilt and sadness rush through me. He quickly wraps me in a hug and those feelings are disintegrated by the warm feeling of happiness and warmth.
"Maybe later we can do that." He whispers. "If I did that right now, it wouldn't be a very special first kiss now would it?" He tucks a loose strand of hair behind my ear that I hadn't noticed had fallen. He walks away and I watch his tall, masculine physique disappear.
Wait a second. How did he know that I have never had a kiss from another person before?!
