Star-Crossed 2014 Complete Series

Plot:

When an alien spacecraft lands in 6-year-old Emery's town resulting in an immediate battle, she befriends one of the young Atrians, whom she helps until authorities capture him. Ten years later, a group of Atrian teens is allowed to enroll in the high school to test the ability of the two species to mix, and Emery learns that Roman, the boy she helped, wasn't killed -- as she had thought -- but kept in an internment camp with the rest of the aliens. The two rekindle their relationship, while animosity continues to grow between the two communities, putting Roman and Emery's bond -- and the chance for peace -- to the test.
