Kazushi Sudou has known sisters Ayane and Kotone Shirakawa for so long that being together feels completely ordinary. A series of increasingly intimate situations reveals that the relationship among the three is no longer as simple as they pretend. Kazushi is drawn to each sister in a different way, while Ayane and Kotone hide feelings complicated by jealousy and the fear of losing the closeness they already share. Their familiarity makes physical distance easy to cross but honest conversation much harder, because any choice could change years of comfortable friendship. Once the boundaries they relied on begin to disappear, all three must decide what they actually want from one another instead of allowing secrecy and desire to make the decision for them.
