Miyuki and Mikari Kiyona are sisters. They are complete opposites. Mikari is perfect, pretty, smart, and everything that Miyuki isn't. Miyuki on the other hand is not pretty, smart, or perfect. Mikari would stand up for her sister when she gets bullied and Miyuki secretly appreciates it, but shows no emotion at all. These sisters go to the same school where the 5 popular boys are at. Miyuki downloads an app and found it strange. It wasn't like any ordinary messenger. They then see the 5 popular boys in that app, which makes the sisters curious. What will they find out? What will happen next? (SOMEWHAT BASED ON MYSTIC MESSENGER)
