Time Travel Star Life

After reading a few chapters, it turns out that I have a real sister who must be brought with me in pig's feet, and I have to forcibly tie several roommates in the dormitory together, which is equivalent to having at least one main line and three branch lines, and then the protagonist can be all-round, be a screenwriter, a director, an actor, a singer, a planner, etc. Later, I will probably get the brothers from the dormitory to start a company together and share the shares. I will spend tens of millions of words on these themes.
