You keep shaking your head, as you were stress to see the actor you had chosen doing a horrible job portraying the main male protagonist.
This is your favorite actor, how can he do a terrible job? You keep thinking about these thoughts. You begin to regret for not choosing Ohno Satoshi to play himself for the drama.
A character that is based on himself would obvious know what to do in certain situations. However (Your favorite actor here) has a different personality than Ohno Satoshi who you wrote about. Being able to portray Ohno Satoshi is too hard for any actor to do.
Knowing that your drama is going to be a complete failure, and you don’t get the guy in the end. But you got to see your favorite actor live and in action. Maybe you could get an autograph from him before the drama ends. However you hope that there will be a second chance for you to change your mistakes unless you are happy with your judgment.
