Peninsula: I Want to Be a Singer

I've already signed a contract to write a Korean entertainment novel and don't want to write about the Chinese entertainment industry, so I can only write about the Korean entertainment industry. It's roughly like this: The protagonist's dream of becoming a singer was shattered in his previous life, and then he transmigrated. In this life, as a third-generation chaebol heir, he wants to be a singer, so he becomes an actor. And because he's an actor, he does this and that. That's roughly it; the group disbands. I'll revise the synopsis later if I find a better one; yes, there's a section I stole.
