악의 꽃

Se-Joon and Se-Wa are twins whose closeness unsettles everyone around them. Se-Wa, written off by classmates and neighbors as unstable, sees no one in the world but her brother and will not tolerate anyone else holding his attention. Se-Joon insists that what he feels is ordinary sibling affection, though his own behavior keeps hinting at something closer to hers. When their childhood friend Su-In comes back into their lives, the sealed world the two of them built starts pulling apart.
