Yes, she is wrong for using the male lead as a coping mechanism from for shit marriage. But the male lead is an adult and he knew what he was getting himself into. He saw that she was previously married. He even knows that if he were to tell her his feelings everything might end, he is choosing to go trough the pain and the female lead doesn’t want that anymore. In my opinion both of them need help and i also hope the ending is a happy one. Although from this latest chapter(32) I doubt that will happen.
Thank you for the updates
