Today is So Ri’s grandfather’s memorial day. On this big day, So Ri learns from her mother that she and Ha Ru are blood-related. So Ri also finds out that her grandfather wishes Ha Ru to be officially added to the family registry, but she will not make that happen for the sake of Han Byeol’s future. As the time for the memorial rite approaches, the Parks and the Ohs gather only to cause more trouble. (Source: Kocowa)
