Lala’s life turns upside down. Not because of the beautiful jump from the ten-meter tower, not because of his father who trains her hard, but because of his first love. Yudhis, a new student at her school, manages to frame up Lala’s heart. In the last year of her high school, Lala is pulled out from her old routine. Her life is no longer merely seeing the blue water of the pool or the dullness of the school walls. Lala believes love has freed her, because Yudhis always swiftly gives rainbow if Lala promises to be with him forever. But slowly Lala and Yudhis must face that their love can bring darkness. Yudhis’s initially simple and protective love turns out complicated and dangerous. Their promise to be faithful forever is a trap. Lala is now floating in questions: what does love mean? Is it like a beautiful jump, which if it fails, should he keep trying again in the name of loyalty? Or is he just drowning in futility?
