The Bloody Secret in the Iron Box

Her iron box is filled with hidden secrets. Seventeen-year-old He Na always carries a rusty iron box with her. No one knows what is hidden inside. But only she knew that what was locked in the iron box was the truth that could tear the entire family apart. Secretly taken photos, deliberately cut newspaper fragments, an earring engraved with the word "hi"... Everything points to a carefully woven conspiracy. And when the iron box was finally opened, no one could predict who would be swallowed first.
