Episode Title:
Lingering Winter.
Episode Description:
A month and a half after Koshiro has moved out, both the siblings are still thinking of each other, but keeping their promise not to see each other again. Nanoka sometimes walks by his workplace, but avoids meeting him. Kaname has taken to sleeping over at Koshiro's apartment because it is closer to their workplace than her apartment. One day when they are going to his apartment, they see Nanoka outside. He pushes Kaname away to hide from Nanoka. Kaname objects to the rough treatment. She guesses that he left home because of Nanoka, then chooses to laugh it off as "every family has its problems", before jokingly relating Odagiri's theory that Koshiro might have been acting inappropriately towards Nanoka. Koshiro snaps and angrily says enough to give Kaname enough of the true picture. She confronts him, accuses him of perversion, and walks away. He stays home from work the next day because of this. When he opens his front door to make a second trip to the store, Nanoka is standing there.
