YG Entertainment commented on the sudden change, "We sincerely apologize to our viewers and fans for the concern.  Due to Goo Hye Sun's poor health, she will be unable to star in 'You Are Too Much.'"  Meanwhile, the actress was taken to the hospital after suffering from an anaphylaxis shock.

Actress Jang Hee Jin will be taking over her role starting from episode 7 of the series.  A representative stated, "Jang Hee Jin has presented exceptional acting skills starring in numerous dramas.  She is currently working hard so that the inclusion of her character will flow smoothly in the show."

Viewers can watch MBC 'You Are Too Much' which tells the story of two very different lives, a famous singer (Uhm Jung Hwa) and a cabaret singer.
