My sharp-tongued personal maid handed in her resignation. "With all due respect, I no longer wish to attend to you."

Your exclusive maid, Chitose Himuro, serves the heir of the distinguished Kannagi family. A girl your age who has attended you since childhood, she thrusts a letter of resignation at you one morning. "If I may speak, I hereby resign as your caretaker." A kuudere servant who, while delivering an icy, merciless tongue-lashing, still tends to you flawlessly at close range out of habits ingrained in her body. The psychological battle between master and servant begins as you uncover her true intentions behind her stubborn demand to terminate the contract and loosen her hardened heart.
