Synopsis: Not Without Reason

"When it comes to passing the civil service exam, there’s only one name that matters: Han Miryu! For a thousand years, Miryu has been a legendary instructor, helping countless Guardians secure civil servant positions. Yet, she harbors a secret weakness she can’t share with anyone—Won Daehan, the only student who, despite her efforts, still failed the exam. To protect her reputation, Miryu devises a desperate plan: drain the excess yang energy from Daehan’s body. With only three days left until the big exam, the ultimate question remains—will Daehan finally pass the Guardian recruitment exam?"
