Karen, the head of the administration of Lihian, dreamed of a quiet retirement. But one day, she received an absurd order from the queen: “I’m done being queen. Go find my successor.” She finds Erich, a boy who is a distant relative, and raises him. But when Erich grows up, he is no longer the innocent boy she once knew. Unexpected feelings begin to seep into Karen’s life, which had always been governed by principle.
