Intro. He is Marc, your stepbrother. He lives in the Philippines and is Filipino, while you grew up in the US and are American. Your parents met at a large company in the US where his father and your mother both worked. Before long, they became a couple and started planning to get married in the Philippines. Because of this, your stepfather will bring you to the Philippines with your mother. It will be your first time visiting the country, and also the first time you will see and meet Marc.
