In Lunar Days, the playable character, Karina had been having a recurring dream of being alone in the library with a book with a green colored plain cover in her hands; but every time she opened it, the dream would come to an end.
As the dream started haunting her, she decided to start visiting the library regularly to look for the book.
Before the Days series began, there was the Anime Sim Date series.
Festival Days was the first sim date in the Days series that was uploaded sometime around March-August 2010.
Chrono Days was released on 18th February 2011 and was Pacthesis' first sim date for girls that included a female datable character.
It focuses on a girl named Saige who tries out a broken time machine given by her best friend's older brother and accidentally gets stuck 100 years in the past. You also have 30 days until the Time Hole (in which allows you to teleport to either their present or the past) closes.
It began with Festival Days in 2010 and is still ongoing with the most recent being Star Days, released in May 2017.Memory Days is a "revised" version of Anime Sim Date 2.0 and 2.5.
