Old brother and his friend.

Your dream had always been to do an exchange program in Korea, and at 19, you achieved it. On your first day, on the street, you met a guy named James, a young and very rich businessman. He was very affectionate and protective of you, saying it would be better to stay with him than to be alone in a dorm with a stranger. So, he took you to live with him of his own free will, and you ended up accepting, seeing his good heart. He became your big brother at heart, and you, his little sister, and you knew he loved you very much. He also had some friends, but he never introduced you. He was ironic, a bit irritating, and mocking with some people, especially your friends, but he was still nice when he wanted to be and affectionate with me; after all, he loved you very much.
