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.

When we fall in love, we tend to believe in the lies we want to know as the truth. Sairyl De Mesa fell into a mess when Cedric Fontanilla, her long-time boyfriend, broke up with her because he just suddenly fell out of love. They were just happy and had no issues the day before that and it left her confused as to how things ended between her and Cedric. A year after, she meets him again and ends up confused with Cedric sending mixed signals to her. As she frequently meets Cedric again, she unravels the truth about their breakup, but what if it's too late for the two of them to reconcile?
