As the only son of a leading business family in country Z, what an enviable wealth and status this is. So in a family without love, would you still feel happy? A family that was not formed because of love. The two people who gave him life left early. Fortunately, he had a strong enough grandfather. Otherwise, what would he have been like? When the first ray of sunshine appeared in his world, he didn't know what it was, but he knew that he would lose it once he let go. What is love? I only know that I will not let go.
