Sreana Vergara, the most famous student in the university daughter of the richest man/woman in the city, people called her "social butterfly" she's very outgoing and loud, louder than a speaker, always at the bar, club, hanging out with different people from any different university, her parents don't pay so much attention to her due to their so called "job"

Zachary Rivera, DLSU? yup that's right! DLSU Lasalle, his family is one of the richest people in the country, like Sreana, Zach is an outgoing person, but he prefers his study more to make his parents proud of him, unlike Sreana, you will only see him in clubs and bars occasionally

Sreana, left him for good and chose her career over love, and now she's a successful model/actress. While Zach, he's a successful CEO, Zach let her choose her ambitions over him.
