You could try checking local TV channels that often air Tagalog movies. Sometimes, they might show a movie like this. Also, some online movie databases or forums might have leads on where to watch it.
I'm sorry, I don't have specific information about the love story between Albert Martinez and Maricel Soriano. Maybe they are actors or public figures in a certain region, but without more detailed information, it's hard to tell their love story.
As I don't know the details of their love story, I can't say for sure if there are memorable events. It could be that any such events are private and not shared publicly.
I think your best bet would be to look on Vudu or Hulu. They have a decent collection of various content. Another possibility is to check the official website of the production company that made the love story. They might have streaming options available there.
