Chiaki, Natsuki, Fuyumi and Hana have lived together in the same house for 2 years, growing close. Natsuki is a lively and cheerful 19 year old girl, yet also the most immature. She's loud, annoying and nosy. Fuyumi acts like the mother of the four, she's 24 years old and has an outwardly cold/kuudere personality, but is caring. Hana is the shyest and youngest at 19 years old. She's an Otaku and prefers staying home. Chiaki, 22, is the most normal, popular, and agreeable who has lots of friends.
