Years after their traumatic separation, Nea and Jasmin's paths cross again. Raised in above average circumstances by Larry and Yolanda along with her stepsister Hazel (Shaina Magdayao), Jasmin is the resident shy girl in school and the target of pranks by Oliver Ynares (John Lloyd Cruz), the mischievous younger son of the prominent Ynares clan. As an old money family, Ynares patriarch Roden (Tirso Cruz III) and matriarch Susana (Hilda Koronel) have given up on the unruly Oliver, setting their hopes instead on the bright, intelligent Ivan (Diether Ocampo) to fulfill their dreams of having a politician in the family. But unknown to Ivan's family and his beautiful, rich, and devoted girlfriend Karri Medrano (Angelika Dela Cruz) Ivan has a dark secret that he kept hidden from those he loves, which now threatens to destroy the life he has carefully built. While Jasmin and Oliver's imperfect lives are about to take an interesting turn, an unexpected change comes from Nea, who is now dead set on destroying the life of her estranged father. On the same day that Nea's mother dies, Nea is picked by a strange man who drugs and takes advantage of her. She later finds out it was Ivan Ynares. Jasmin and Oliver break up due to Nea's rape allegations and also because Oliver thinks Jasmin was cheating on him with her childhood friend. Nea goes to court, but before it starts she is bombed by Roden's men. Susana leaves the house and breaks up with Roden when she finds out Roden was cheating on her with Yolanda. In response, Roden vowed to take his revenge on the Fontenellier family.
