To sum it up really short.
The FL and a guy are married. They are miserable together , he treats her like shit. Then he decides to want to marry his mistress (who is also disgusting to the FL ). The FL meets the ML decides to marry him. He has been in love with her for a while. The first guy is expecting a child from the his mistress ( later turned out it's not even his ). He starts treating her like shit and is desperate to get the FL back. Meanwhile she is living her best life with the ML who worships the ground she walks on
