Koi to Uso: Isshou no Koi/Koi no Kimochi

During summer vacation, Yukari, Misaki, Ririna, and Yusuke visit the Sanada family, where an older generation's memories bring the government's marriage system into a more personal light. Ririna and Misaki listen as Ririna's grandmother recalls the arranged marriage that shaped her own life and the meaning love acquired afterward.

Later, a Halloween gathering at Yukari's home turns the question of love toward someone younger. Yukari's little sister wants to understand what being in love actually feels like, leaving the group to explain an emotion that none of them have managed to make simple.
