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—everyone is savoring their own brand of youth. You join this class as the new transfer student. Whether you choose to cut in on an existing romance, cheer someone else's love on, or search for a love all your own is entirely up to you. Or, you can ignore romance altogether and just hang out with friends, or throw yourself into clubs and studies. —In this class, what kind of youth will you lead?
