Summer and Bryce seem to have nothing in common, and the fact that they have to work together in class for a full year just repulses them. An attempt to try to bond outside of school, actually turns into something more. Summer starts to fall for her enemy and their love of soccer evolves into a budding romance.

Summer and Bryce have faced obstacle upon obstacle, and have survived many highs and lows in their relationship. But now with Bryce off to college, will their love survive? Will someone from Bryce's past break them apart? Will Summer be able to coach her high school's soccer team? Will Summer finally be able to get over the death of her dad? One thing is for sure. Love isn't easy...

Summer and Bryce used to hate each other, until they found out they shared the same passion. Soccer. They fell in love with each other. But now as they start yet another year of High School everything seems to be falling apart. The soccer team risks being cut. Summer is still scared from her father's death. Bryce is inching closer and closer to graduating and having to move half way cross the country to go to college, leaving Summer. Now they have to play soccer to keep their teams and to keep each other.

Elena and Cara Morales are the infamous twins of Mark Morales - the governor of California. Now, while they both may be related, like most twins, they couldn't be any more different. Elena was seen as an elite, social butterfly - she's kissed more boys than she can count on her fingers, she's taken part in tons of high school clubs and groups, she has a never-ending list of friends as well as a never-ending amount of Twitter followers, and not to forget, she had the bassist of band 5 Seconds of Summer wrapped around her finger. Yeah, she was dating Calum Hood. Cara was nothing but mediocre - nothing that could even somewhat be compared to her twin. She was ordinary and indifferent and was a half-melted scoop of vanilla ice cream amongst a ton of other wild and unheard of flavors. Kissing (unless it was the asses of her teachers), Popularity, Boys, and Fun weren't words she was familiar with in the slightest - she was outcasted, canceled out. Simple as that. After Elena suddenly goes missing and a secret search party is sent out to look for her, Cara is asked to finally put herself to good use by participating in what they called The Replacement Project. She was to play the role of her sister in order to save the reputation of her family, knowing that if the public were to find out the governor of California actually allowed his daughter to go missing, the entire family would collapse into a pile of ash. It was a solid plan - nobody would suspect a thing. There was only one, underlying rule - don't fall in love with the boy who wasn't really yours to begin with.
