Overview

After their parents' remarriage, the same-aged sisters I-seul and I-jin live in different cities following their mother's death. I-seul, escaping her abusive boyfriend, goes to visit I-jin in Jeonju, but the two struggle with unresolved feelings toward each other. When I-seul suspects that I-jin is hiding their family relationship from her friends, she lashes out in anger, while I-jin feels suffocated by having to act as both older sister and mother to I-seul.
