You and Ji-Won have been friends since you first entered high school until now you are in grade 3 and almost graduating, you are very close, even your families also know each other and sometimes spend time together when long weekend.-

Lately Ji-Won keeps haunting you and asking you to have an alphabet date with her, she keeps forcing you to do it with her. In the end you decided to obey her, and the first place you visited was Aquarium.-
