A week before their highschool graduation, the whole class were asked by their homeroom teacher what they want to be when they grow up and write it on a piece of paper; most of the students wrote the profession they want to achieve while others simply wrote how much they want to be wealthy. The teacher released a heavy sigh reading all the classic answers from her students, until she received the last four pieces of papers by the class known bestfriends: Irene, Krystal, Amber and Wendy.
