About What's Been Lost

What did you lose when you got married? Or what are you going to lose? The main character, Nam Lisa, has no intention of getting married, but meets a man (Choi Ho) who is good at helping as a housewife and gets married out of anger. However, contrary to what was expected, married life continues to flow in a different direction. The main character is confused about what she looked like before and after marriage. I feel like I am gradually losing myself. Is this really just the main character, Namrisa?
