The Heroine Wants a Divorce and Doesn't Want the Child, but They Get Back Together Later

The child favors the male lead and often breaks the female lead’s heart. When the female lead decides to divorce, she doesn’t want to take the child. The child keeps crying and asking why Mommy doesn’t want him. Later, the male lead pursues his wife and they get back together, but it’s fine if they don’t! Something like "After Divorcing the Movie Emperor, We Became the Nation’s Favorite Couple".
