A happy love between Darkness

OLD SUMMER TRILOGY #1 Estella and Yori have always been rivals ever since high school because of debate competitions. They would always switch places for years until Yori transferred to Estella's school and both of them became members of the debate team. They may not be competing against each other in the debate anymore, but they are now competing for the honors and the top student spot. From enemies and academic rivals, they find themselves falling in love in a series of summers.
