I think mc will stick to be an actor because he doesn't have good experience being an idol. that's why in the first chapter he's happy to get a role even it was an extra to be an actor then get hit by a truck and also when he go back in time, he immediately choose to be an actor as his career and reaching to be a full time adult actor by starting as a child actor. So by the time he reach adulthood he has acting experience by being a child actor.
And our MC is going to be a lot or at least a little bit more grown! Maybe his middle school/highschool era?? I think he's already in middle school! It will be interesting if he maybe tries a badass role in an action film like Bloodhounds or Weak Hero Class! Or maybe he'll pursue his dream of his first life and try to debut as an idol?? Handling idol and actor at the same time is NOT easy though. Maybe he'll stick to actor. We'll see.
