How it all started - Clexa au

It all started 2 days before college, and Lexa has terrible nightmares from her past, she wakes up every night screaming and crying. She had to leave her mum and everyone she loved behind for a while to go to college. Then she met her roommates, Raven and Octavia. Raven and Octavia are sorta popular and have a bestfriend named Clarke. Lexa really liked Clarke and feels some kind of spark that lights up when she's with her, Clarke doesn't know if she likes lexa. Both girls unable to solve their feelings for eachother, while same with raven and Octavia.
