Transmigrating Through Various Worlds of Film and TV

Su Ran was an orphan from a young age, but through hard work and perseverance, he eventually built a company of his own. Then the girlfriend he had always cherished betrayed him, leaving him bankrupt. With nothing left, he chose to end his life, only to be selected by a System before he died and transmigrate to different worlds. The first worlds include The 28 Rules of Love, You Are My Glory, and Fireworks of My Heart. Sometimes the protagonist becomes a character in the story; other times, Su Ran appears in it as himself. It depends on the world.
