My Janitor, My Guardian [ninja janitors, mafia princesses and cute romance]

Regina Komanov writes stories about adventure and romance, and she's come to terms with the fact that she will never live one of her own.
This all changes one day when she sees the school's handsome janitor single handedly destroy three mysterious men in suits. Suddenly she is sucked into what sounds like a story of her own as she solves the mysteries surrounding the janitor who's taken a sudden interest in her, and her own confusing feelings for him, the men in black who keep snooping around her town that seem all too familiar, and her own past.
