【Updated Daily!】One day, a love letter arrived for Nazuna Haimiya, a dead-eyed loner.

Though skeptical, Nazuna answered the summons and headed to the back of the school building.

The one who appeared there was Akane Hiiragi, said to be the most beautiful girl in school. Upon her arrival, she looked at Nazuna's face and said:

"I'm sorry, but I can't go out with you."

Akane left after saying only what she wanted to. Nazuna, too, dismissed Akane's actions as a bad dream. However, for some reason, the two found themselves living together starting the very next day, and what's more, Akane had five equally beautiful sisters.

With nowhere else to go, Nazuna desperately tries to befriend them. The sisters, too, are gradually drawn to Nazuna. ...However, they harbor a secret they can't tell anyone, and Akane schemes to drive Nazuna out to protect that secret.

A delightful romantic comedy, spent with a unique set of sisters, begins here!
