House of the Sun

たいようのいえ

Mao Motomiya is a shy high schooler who feels unwanted at home, where her mother left and her father has remarried. When she reconnects with childhood friend Hiro Nakamura, a young programmer living alone after his parents died and his siblings scattered, he invites her to move into the half-empty Nakamura house. The two grow close again as they keep the household running and hold out hope that Hiro's brother and sister will one day come home.
