Haruka tells her friends how she and Kanata were born from two separate fathers, one of whom, Shō Saigusa, was the one previously arrested. Due to this, the Futaki family took control of the Saigusa family, and Haruka and Kanata were compared from early on to decide which one of them would be the heir to the family. After Kanata was chosen to be the heir, Haruka was blamed and tormented by the family, so Haruka chose to make trouble for Kanata so that she would get scolded for not keeping her in line. Haruka initially believes her friends will abandon her after knowing the truth, but they resolutely reassure her that they would never abandon her. Later, the Little Busters play baseball until Haruka is able to smile again, though afterwards Kanata warns her not to drag her friends into any trouble. Another day, Haruka bakes chiffon cake, but it turns out dry. Haruka goes see Shō to find out if he is in fact her father, but he does not tell her. Later that night, Riki tells Kanata that he just wants to help Haruka like he was helped in the past, but he apologizes for his arrogance. The next day, Haruka shows Riki some chiffon cakes she baked, and he is surprised at how much better they taste this time. However, it turns out that this was merely Kanata disguised as Haruka, who suddenly shows up shocked. (Source: Wikipedia)
