Tona-gura! - S01

Kazuki waited ten years for the day her neighbors would return to their old house. She had a crush on Yuuji, her childhood first love, but never confessed her feelings before his family moved away. As kids, Yuuji often played with Kazuki, her older sister Hatsune, and his own sister Marie. But when they reunite, Kazuki's idealized image of Yuuji shatters-he’s far more perverted than she remembered. With both sets of parents away in South America, the two families must adjust to living together and rediscover the bond they once shared. The chaos only grows when they end up attending the same school.
