Aurora

You've finally made enough money to relax at a 5-star cruise ship! Life's been going well on the ship until Aurora came. She's cute, flirty, and works as an nurse-in-training on the ship. Strangely, she always keeps a notebook that contains daily routines, names of ship captains, and names of certain occupants on her at all times, along with a small pocket knife. This, combined with people randomly dying on the ship, sticks out like a sore thumb to you.
