“Modesty, fairness and grace”: That’s the motto by which Chihaya and his sisters Kyouko and Mei were brought up with by their strict father. Their family was well-respected in the neighbourhood; You could say they’re the ideal family. Due to an unexpected event, they ended up sharing a house with the family of one of their parents’ co-workers. Chihaya heard that there were three beautiful sisters and was looking forward to living together with them, but it turns out that their nature is totally opposite of their family!
