Actor who changed his ways

I've lived 10 years regretting those arrogant days... Do-yoon, a washed-up actor who finally seizes another acting opportunity, pours his heart into it. But then, a terminal illness strikes him out of nowhere. Just as he's about to give up on life, he gets into an accident while taking the place of a young girl. "Ah... if I start acting again, I can really do it..." When he opens his eyes, he's on set!? "I'll show you. What acting is. What it means to change!" Face is face, aura is aura, acting is acting! A story about a once-arrogant actor's true heart and full power, reincarnated as an actor!
