This story is supposedly centered around a tragic love story but in truth, I would rather say that it is a family drama spread over a decade.

The story is quite complex and long, but it all starts with Yoon Na Moo. He is a studious and upright young man, who meets Gil Nak Won, a newly moved neighbor. What should have been the beginning of a tender love story between young teenagers quickly descends into hell, and all because of Yoon Hui Jae, Yoon Na Moo's dear father. You see, Yoon Hui Jae is a psychopath and serial killer, over the course of his life he has killed women with no motive. This man who only gives value to strengh, has two sons, Yoon Hyun Moo is Yoon Na Moo's big brother. Yoon Hyun Moo is basically a bully, but this is more complex, in truth, he is a character who has lived with the suffering of not being acknowledged by his father. Considered a "weakling", he never received any degree of attention. So, he's acting out, trying to attract the attention of his father, but also his stepmother who cared for the two boys. In contrast, Yoon Na Moo is the son cherished by his father, whom he holds in great esteem, since he was very young.

With that said, Yoon Hui Jae, the father considers that any kind of love and affection that his beloved son receives is holding him back, making him weak. This leads to a terrible Christmas night where the father murders Gil Nak Won's parents, and attempts to kill her too only to be stopped by his son, who defends Gil Nak Won against his father, calls the police, and later testify against him.

We then follow the characters over the space of 12 years, as they grow up and try to live with the terrible memories of that night, still mysterious to the public. Yoon Na Moo tries to atone for his father's crimes by being a police officer.

The story becomes more complex when murders by a serial killer begin and a stalker tries to take Gil Nak Won's life.

The series initially relied heavily on flashbacks to emphasize the relationship of each character, their motives and actions. The characters in the family are well developed. And if at the beginning we are carried away by the love story between Gil Nak Won and Yoon Na Moo when they are young, and which continues over time, quickly the family relationships in the Yoon family become the center of the intrigue and the main engine of the series.

Despite how fucked up the characters are, discovering the obsessions and unhealthy relationships they have, I can't help but have affection for them. Whether it's the mother-in-law who fled with her little daughter, witnessing Yoon Hui Jae one night with a bloody face, and who is trying to make up for leaving the two boys behind with their father. The big brother who tries to repair a family that no longer exists by committing crimes but also by sacrificing himself. The little sister who loves her two brothers unconditionally. And the more fascinating one of the psychopathic father with his youngest golden son.

This is an intricate and tragic web to behold.

As a final mention, I must say that I loved hearing the pronounced dialect of the main characters, I found it very charming.
