Relationships are often based on circumstances and (mis)understandings. We are always surrounded by circumstances beyond our control. Our birth establishes limitations and pathways.
Pigs play a role in the story. We first see Jin Young-soon being proposed by Choi Hae-shik accompanied by a baby pig. They operate a pig farm as she becomes pregnant. Although an honest man Choi Hae-shik crosses a gangster and a corrupt prosecutor which results in his death, with the viewers well aware he was murdered, however the culprits get away with it. Years pass while her son Choi Kang-Ho becomes very studious while his mother restricts him in many ways in her way seeking revenge for her husband's death. He has a girl friend Lee Mi-joo and they are close until he breaks up and shortly makes moves to get close to both murderers of his father. This all happens in the first two episodes which ends with an accident that renders Kang-ho as an amnesiac with the mentality of a seven year old. Many ups and downs follow with lots of misunderstandings and surprises.
There is comic relief among the neighbors of Jin Young-soon who provide their own sub plots. Pigs provide her livelihood, but are resented by many resulting in a fire. The viewers are told that pigs are naturally clean animals and have one unusual limitation--they cannot lift their heads to look up.
