The complicated love story between an introverted guy and the most popular girl in school continues! It's been nearly two months since Ryuto and Runa started dating and their relationship continues to grow in unexpected ways. During the summer vacation, the two end up living together at Runa's great-grandmother's house by the beach - and the upcoming summer festival means the opportunity for the two to experience even more firsts in their relationship. Plus, there's more excitement for the two teen sweethearts when Ryuto invites Runa and her friends to battle them at Airsoft.
