In a house, there are three people: a young married couple living with a father over 50 years old. Despite his age, the father still shows his strong health. The son works from morning till evening, while the daughter-in-law diligently takes care of the household chores. To outsiders, it may seem like this family is living happily, but in reality, it is not the case. The husband unfortunately suffers from infertility, making it difficult for them to have children. The wife longs to have a child to bring joy to their home. The unfortunate situation leads the wife to not be able to fully devote her heart to her husband and instead she ends up having an affair with her father-in-law, in search of hope and a different path to achieve her dreams. But what will happen tomorrow when the husband finds out that the child is not his but his father's?
