The happy ending I personally want for her is no longer feasible the moment she came back from overseas. She could've chosen to live the rest of her days with her employer and they were absolutely fine taking care of her after all those 39 years of remaining with the family, that's like 2 to 3 generations worth of loyalty but she opted to live in the Philippines for retirement, in a way, she had pride as a worker that she knew her body wouldn't be able to handle the daily chores anymore and despite having that safety net, she opted not go back and this is her ending. Bad things happen to good people and even more so to people that don't even deserve it.
