This is the dramatic ending of a teleserye, the final chapter of a book, or the end of an era. It’s more formal and final than `matapos`. When a story `nagwakas`, it means "and they lived happily ever after"... or not. It’s the "fin" at the end of a French film. It carries a sense of finality and destiny. Parang 'yung relasyon n'yong bigla na lang... `nagwakas`. Ouch.
