Mio is a mute underclassman of Kōhei's with abundant expressions. Since she cannot speak, she uses a sketchbook to carry on written conversations. She belongs to the theater club as a junior of Yukimi Miyama. While she performs non-speaking parts, she handles her own role reliably. She is quite a dojikko, an anime stereotype for klutzy cute girls. Other than the sketchbook she uses, she has an older sketchbook which she treasures greatly.    From Wikipedia.

Orihara Kouhei returns to his town after a long disappearance to fullfil the promises he made to several girls in his childhood. He suffered from memory loss, and carries a tragic past.

In 1998 winter, another world happens to come to existence in me, though I used to be a normal student. It is covering my ordinary life as the snow covers the ground. Until then, I haven't noticed, what has stayed unchanged in my daily life, the familiar scenes that have always been there, the warmth of the person whom I haven't noticed that I love her. 
They have existed to bind me in this world in order not to let me leave. 
It is the moment when I begin look for the bind and the significant person, for the first time. The time goes, and the sun gradually begins to shine the season. I wonder where I will be, and who will grip my hand.
