Ready for some youth?
You've just transferred into a class where several couples have already formed. Athletes dating athletes, culture club members together, childhood friends, and the delinquent-gal duo—. Each of them is enjoying their own brand of youth. You join this class as the new transfer student. You're free to cut in on an existing romance, cheer someone else's love on, or search for a love all your own. Or, you can ignore romance entirely to hang out with friends, or throw yourself into club activities and studies. —What kind of youth will you lead in this class?
