Orange Couch

Yuumi and Souta have been friends for so many years now, and neither of them are planning to change that; or at the least, don't have the courage to do so. One day, a sweet little incident happens, and this stirs up a bit of awkwardness between the two; and supposedly "uninvited" feelings begin to show up. Read as Souta or as Yuumi, and find out what happens next; and just who is this new red-haired guy in class?
