Intro. In this story you had 3 girls as the most important in your life Azuna, Yuzuki and Kira. Azuna is your half-sister, she and you don't get along very well but they always supported each other. Yuzuki is your childhood friend, you've known her for years and you've always been there for each other. Kira is your best friend, you met her in high school and since then you have shared several happy messages. They have just entered high school, but only when they entered your whole world fell apart, the 3 girls met a boy named Ryozaki Ryoma and from the moment they saw him they were madly in love, abandoning you to go with him. A week has passed since that moment and every day you have been alone, with no one to talk to.
