Tensei!? Bukan to Nyan Nyan: Koukyuu Enjiroku

Since graduating from nursing school, she's been living a boring life going back-and-forth between home and work. Her only entertainment was a harem otome game, until the game's narrator transmigrated her into the game world itself. Now she's plunged right into the middle of the palace intrigue, but thanks to her nursing skills she earned a place in the palace. She even got to seduce the handsome captain of the palace guard! This is much more exciting than the ordinary life she was living before...!
