Game drops a boat-load of errors when you choose start. Ignoring all of them (as in choosing ignore on the error page over and over), it does work. The dialogue seems very bland and forced, grammar errors aside. I can see potential with it, but don't rush the progression so much with the story. Even though the demo was so short I still felt it was extremely rushed.
Allow the reader / player to get a feel for the characters and their personalities. Having the characters be like "I'm an idol with my own show." "I hire idols." "Hire me?" makes no sense. There would be a lot of deep discussion as the self-proclaimed idol feels out whether they can trust the MC who claims to be an agent.
It also makes no sense that she would even consider working for him as she stated she had her own show and was already an idol, which means she has an agent already.
