This is based on a recent news item that the mother left to work abroad while the father stays at home. The children got better grades because of the better life that the mother had provided. After sometime, one of the child discovers that their mother has a boyfriend abroad. It is a family drama that did not have a happy ending. The crux is that the mother left for working abroad.
This is a common drama in real life among Filipino as far as I know. And the dismal scenario of said situation, the family is broken. The children's future is affected. As what a line from a local popular song said, "O kay pait, kuya Eddie." Putting it humorously, when the cat is away the mouse will play.
Well that already depends on the preference of the mother if she will stray or not, at the least she will have to give support to her kids until they are old enough to be independent.
