Si Mar ay galing sa mayamang pamilya.. Napakaarugante, napakasama ng ugali, napaka-playboy, napakatamad, lahat na ng napaka nasa kanya na.. Lalo na yung NAPAKAGUWAPO.. Samantalang si Mae naman ay nasa simpleng estado lang ng pamumuhay.. Napakabait, napafriendly, napakatalino, napakamapagmahal at higit sa lahat NAPAKAGANDA.. Para silang aso't pusa kung magbangayan but then one day they suddenly feel something for each other.. They fell inlove.. Akala nila they will be forever happy as they promised each other but one tragic moment came.. If only they can turn back time kung saan mababago nila yung mga pangit nilang memories at palitan ito ng masasaya.. If only they can have second chance to express how they were so inlove with each other.. If only?
