One

Marlo Jackson, she was a introvert always kept things to her self,shy, didn't like being in crowds,she just wanted to be by herself most of the time.

Kian Lawley, he was the new kid and the complete opposite of Marlo. He didn't want to be by himself,he was social,he was an extrovert. Therefore you would never expect them to even talk,but they do. Kian was changing her slowly without her even knowing,that wasn't the only thing that was changing.

The way they felt for each other changed dramatically,but again that isn't the only thing that was changing.
