This is a parody game with some characters based on those created by MrDots for Dating My Daughter. If you've played DMD you should be familiar with Dee's past: My Naughty Daughter is a fantasy variation after she moves to Seaside with her father. Although MND shares some characters with the game that inspired it, how they interact, their attitudes, relationships and recent events are now different in this parody work. For example, Dee is the Main Character in MND, much less shy and naive than in DMD.
