It's a thrilling drama. In the beginning, the protagonist made a mistake with his friend, he knew about his friend's feelings and still approached the young woman. The drama shows the mistakes of several characters, and it is sad to see some become bad people over time and others suffer from the consequences of their choices and mistakes and have an unhappy marriage. I wish they had focused a little more on the protagonist's romance with the doctor, there were many episodes of him liking the other character. It would be interesting to watch them in another drama. It's an incredible drama.
