Before the Days series began, there was the Anime Sim Date series.
It shows that Marty and Prince Dreamboat met at the gas station, when they were filling up their cars.
The game is pretty unique compared to the others Amy makes, because usually the mission is to get a date.
Here, you have to make yourself irresistible before the week (7 days) is up, when you have a date at the park with Prince Dreamboat.
It is about a princess named Rose who is forced to flee her kingdom with her elf servant, Lewis, when it is attacked by a neighboring kingdom.
They wander through a forest till they see on a castle and knock on its door and meet a king who will not let them stay unless Rose marries him in 30 days.
