Once graduated from high school, Yo-Yo says he's going abroad to study some languages. He doesn't want to be stuck in Japan for the rest of his life. He wants to be able to do whatever he wants with his life, and he wants to make sure that Miharu is impressed with him. Miharu, however, isn't so sure about this plan. She's worried that she'll have to take care of her mom while she's abroad. She also worries that she won't have enough time to care for her three-year-old niece, who's getting older by the minute.
