Momohara Nacuki wa settoku suru (S03E05)

You head home to the country for the first time in a while and your younger sister Natsuki greets you with open arms. She praises you for how hard you've been working and living alone in Tokyo, but she tells you that she's also wondering if she should go to Tokyo for high school. On a cool, summer night, Natsuki tells you her dreams. (Crunchyroll)
