Heart Beat
Friends are the best brothers.
Keira, Agatha, Aluna, and Lexa are united because of their love for music. The differences in characters and backgrounds at first really made it difficult for them. Not to mention the problems from each of their families that make their friendship like strains of sadness. All lost with their music hobby. Then they also meet Lido, Lexa's best friend, and Biru, Aluna's lover.
