It was decided romance was distracting so they held back at the beginning. The main characters certainly had personal problems. Hyo-min, the female lead we learn was a twin whose sister turned out deaf and had been given to an aunt who was also deaf. When a lover found out about this he broke off their relationship. Romance is subtle and slow to develop.
A tool for a possible romance is a dog. Early on you will learn Seok-hoon the male lead and mentor to Hyo-min has been divorced and shares custody of a dog. He fusses over the dog and is very concerned for its well being.
What makes the series worth viewing, is the cases and how the lawyers peel away the issues to find out what really happened. Ethics are discussed. A few examples follow.A man breaks into a fertility clinic and destroys some expensive equipment. The clinic sued him for damages, but realistically that was beyond his means. His motive was that he had come to them before an operation with a risk of infertility. The operation saved his life, but he did become infertile. And later we learn that his wife was desperate to have a child that would not have a disfigurement that she got from an accident. The back story was important for the case and Hyo-min is the one who uncovered it despite the accused client's wariness being interviewed by a woman.
In another case Seok-hoon was forced to work with a client that repelled him. Nonetheless he is very good at getting the client out of some messy situations. You can't help but think life is unfair when despicable people can get away with bad things. Obviously money plays a role, but not the only one: http://www.therealjohndavidson.com/2023/08/untouchable-how-they-get-away-with-it.html Our hero does redeem himself.
In an assisted suicide case we learn the husband had had an affair and stood to inherit her fortune. But we and the court come to appreciate the wife was suffering and he really did love her more than some greedy relatives.
In the episode "Bystander" we learn a little of Hyo-min's history that involved watching someone being beaten up and did nothing. One of their cases involves a similar situation and as viewers we come to appreciate what a big factor ignoring someone's suffering can be.
Each episode brings a difficult case demanding careful analysis and moral judgments.
Typical of Korean series there are some personal relationships among the staff as there would be to some extent with all legal teams.
