While tracking a criminal, Kim Ieum discovers a man collapsed on a mountain road. "How can there be no fingerprints or DNA?" The man, suffering from amnesia and believing himself to be a child, cannot even be identified. Kim Ieum, with nowhere else to send him, takes him home. She names him 'Yeongsik' and decides to live with him. "Mister, do you dislike Yeongsik?" "I don’t dislike him. Yeongsik is such a good boy." Contrary to his cold appearance, the man is gentle. Ieum only sees Yeongsik as meek and innocent... Then one day, left alone at home, Yeongsik looks at Ieum's family photos with an amused expression. "F***, I walked right into the tiger's mouth?" His memory has returned.
