Beloved children, Mine or someone else's family

Jamie Lockwood tried to be a good husband to Laurel. But when she became addicted to alcohol and fell into a protracted depression, he could not bond with her friend Sarah Weston who not only supported him in difficult times, but also shouldered the burden of responsibility for Maggie, one-year-old daughter Lockwood. Jamie Sarah was born a son, Keith, whose origin has decided to keep secret.
Years passed, and now children have to deal with the past of their parents. Keith and Maggie hate each other, but they have to unite to uncover one family secret, and to return to the home of love and peace.
