Ever since they were little, Jun's charismatic younger sister Ran has had a habit of "borrowing" her favorite things and making them her own. It always annoyed Jun to lose her toys, clothes, and other belongings, but she saw it as just part of having a younger sibling--until the day Ran claimed her boyfriend, too. The two haven't spoken in eight years when they're reunited at their mother's funeral. Ran and her husband--Jun's ex--want to move into the house their mother left behind, but Jun will be damned if she lets Ran take one more thing away from her. With neither side willing to budge, the three find themselves living under the same roof, and it's not long before old resentments, secrets, and passions threaten to unravel their lives.
