No one said the road to stardom would be easy.

IU, whose character is preparing for her debut, became a victim of bullying as seen in new still cuts from 'You're the Best Lee Soon Shin'.

IU unknowingly walks into the path of her enemies' wrath as her female classmates enter the restaurant where she works and begin egging her. Young Hoon (Lee Ji Hoon) and Jae Bum (Choi Kang Won) come to IU's rescue as they pull the other girls away from the fight.

A representative commented, "During the filming that lasted until the early morning, the passion of the cast who keep their fighting spirit while acting and the staff's effort were amazing. Please look forward to Soon Shin's growing pains, which begin on this week's 'You're the Best Lee Soon Shin'."

Watch to see if IU can successfully make her debut on 'You're the Best Lee Soon Shin' every Saturday and Sunday at 7:55 PM KST!
