If you are interested in our other works, please feel free to visit us on Twitter\.    This is a love story about a girl who is bullied and how she survives in this seemingly isolated world\.  Players can experience the situation of an isolated student and how she interacts with others at school\.    The girl suddenly wakes up to find herself on an isolated island\.   The oppressive sky, the indifferent air, and the malicious classrooms\.   Things that she used to take for granted now seem unacceptable\.   The girl silently makes a decision\.   Can she make some changes in the last three days?   If everything is the same as before,   she will no longer try\.    Game Time: About 40 to 60 minutes  Endings: True End x1、Normal End x2、Bad End x1  Production Team: 小喵、蘋蘋、Papernight、Shiro、Dot、Mag、矓矓矓、Tsun Tsai、Mirai          As our game is non\-profit, we do not have enough funds to hire professional translators\.
