"Hey, just sing one line over and over again. Are you a repeater?" "Do you hear the lyrics clearly?" "Of course I heard you clearly." "What's the next sentence?" "Your figure is so close but I can't hold it." "You're so stupid, why don't you come over quickly?" … PS: This is a story about "guarding", with a single female protagonist, daily life and suspense.
