Cold, disabled, and handsome Inspector VS Beautiful, mysterious, and scheming male oiran. Holding grudges toward each other, they disguised themselves and stayed by each other’s side. This is a story of seduction, betrayal, and restriction. The stirring current of politics, the weird unsolved cases in town, and thousands of sleepless nights... Listen to the whisper of the killer lies beside... Who’s the one attacked first? Who’s the one fell for the other first? They hurt each other but they couldn’t leave each other. Mr. Inspector, my blood can save your life.
