Summer Colored Winter Scarf

Guess where I am? Momo and Misaki are best school friends - nothing can separate them. To start the day together, they are constantly thinking of new meeting places via voicemail. Everything seems to be in perfect order until the day Misaki falls in love with Toru, a classmate from Momo's class. As a best friend, Momo tries to support her friend in her ambitions - they set up a photo club. During the secret snapshots, they come across a book whose plot shows strange parallels to what they did ... the title "Summer Colored Winter Scarf".
