One day during lunchtime, Shingo gathered with four girls who had transferred into the same class as him. His twin sister Yui suggested that they undergo ‘love training’ in order to find a wonderful first love. He thought he had heard her wrong, but the other girls all readily accepted the idea. Thus, the first love agreement was formed. It contained 5 articles: 1) one must report all activities, 2) one can try anything they wish, 3) one should not forestall others, 4) one should tell others if there is any progress in their situation, and 5) if anyone reaches the goal, then everyone else should offer them their congratulations. With the summer festival as the deadline, the girls begin their quest for first love.
