Yuna never expected that her favorite kpop group would come to visit her school. Nor did she expect that she and all of her grade would be spending their whole school year on an international tour/vacation with them to help with their new album Skool Luv Affair. As the vacation starts, Yuna has some feelings for a certain member, but she knows that she isn't the only one. Will she be able to confess before the time runs out?
