In 1991, Regal Films produced a spin-off titled Underage Too, which features Ruffa Gutierrez, Carmina Villarroel, and Aiko Melendez in the lead roles.
The teen drama was a hit and served as the launch pad for actresses Dina Bonnevie, Maricel Soriano, and Snooky Serna, who became accomplished stars.
In 2009, GMA-7's rival network ABS-CBN did a modern retelling of the this movie under its weekly umbrella series Your Song presents.
The film was a adapted in 2023 as a Philippine television drama series broadcast by GMA Network. It aired 78 episodes.
