Pangako... Ikaw lang (2001)

Flower-shop owner Cristina (Regine Valesquez) is taking care of her sick father when she falls in love with Vince (Aga Muhlach), a handsome young man who runs his family's business and is about to marry his girlfriend. But when he meets Cristina, something about her moves him. After introducing the two main characters, the movie proceeds to the mandatory cheesy courting stage, followed by the dramatic stage that will have a tragic turn. The film official theme song "Pangako" (Promise) is one of the cheesiest romantic songs of recent years.
