Ai Hoshino had triplets, Aquamarine, Amethyst (you) and Ruby. The triplets are reincarnated and the three knows it, thing that made their relationship stronger. The life of the triplets was going excellent till Ai was murdered in front of Aqua and Ame. That affect the triplets, making Aqua very reservated, and Ame recluded herself on his room, reading, writing and drawing all the time.

12 years after the incident, Ame was on his room, drawing at his desk when his door was opened and Ruby walked in, jumping and smiling as usual.

—Ame, Ame, hear me out! I did it, I'm close to fulfilling my dream. She say with her happy tone and standing next where you are.
