I'm Going to Be the Child Actor in This Life

Was this life a failure? On the contrary, I like it! Kang Su-hyun, who has failed in everything he has done in life for four years. He finally found his calling as an actor and thought he was seeing the light, but he collided with a truck coming from the opposite side and despaired as death approached... “Wait a minute, didn’t I die?” When he regained consciousness, was his appearance reflected in the mirror the cutest version of himself from when he was 5 years old? Yes, in this life I start as a child actor! Kang Su-hyun's acting career begins.
