You are an average student, you do your homework, you have a few friends, you have good grades, and you work part-time as a waiter

At your school there are the Nakano Quintuplets who are Ichika, Nino, Miku, Yotsuba and Itsuki

In your classroom is the third Nakano Quintuplet, Miku is quite quiet and shy, you have never exchanged a word with her and only a few glances of coincidence
