Lovers or Siblings

Zoey Green and Andrew Thomas meet in a karaoke room. She comes from a poor family. He runs a company and his family has money. Neither of them knows that the other is the sibling each has been looking for, and feelings build between them anyway. Zoey's foster sister, Isabella Green, puts herself in Zoey's place on purpose. Andrew's foster sister, Ezra Thomas, is jealous of Zoey and the jealousy hardens into resentment. With that going on, and with what the two of them are to each other, the misunderstandings and the arguments keep coming. Neither can let the other go, and they hold on to something they have no standing to have.
